Telemarketing still works. In a world of ignored emails and crowded inboxes, a well-handled phone call remains one of the fastest ways to get in front of a decision-maker and start a real conversation. The catch is that the bar has risen. Buyers are busier, harder to reach, and far quicker to end a call that feels scripted or self-serving.
The good news is that the fundamentals have not changed. Get the preparation right, sound like a human being, listen more than you talk, and follow up when you say you will, and you will out-perform most of the people picking up the phone today.
Below are 50 things to do and 50 things to avoid, grouped so you can find what you need quickly. Use them to score yourself and your team, then fix the gaps. If you would rather hand the whole thing to specialists, our B2B telemarketing services and telemarketing training are built around exactly these principles.
What has changed for telemarketing in 2026
The phone call itself has not gone anywhere, but the world around it has moved on. Here is what is different this year, and what it means for the way you call.
| Then | Now in 2026 |
| Manual list research and dialling ate up your day | AI surfaces intent signals, suggests the right contact, dials, and takes notes |
| You reached people at their desk, nine to five | Hybrid working means mobiles, direct dials, and calling at less obvious hours |
| The cold call stood on its own | A credible LinkedIn presence warms the prospect before you ring |
| The receptionist was the gatekeeper | Voicemail and the inbox are the new gatekeepers |
| Clean data was a nice to have | Accurate, compliant data is essential, and still a legal duty |
The takeaway is simple. Let technology do the legwork so you can spend your time on the part no machine does well, which is building rapport and reading the person on the other end. A warm LinkedIn connection, a sharp voicemail, and a fresh, clean list now do as much heavy lifting as the call itself.
If you only change five things this week
Short on time? Start here. These five shifts tend to move the needle fastest.
- Open with your reason for calling, not “how are you today”.
- Aim for a talk-to-listen ratio of no more than fifty-fifty.
- Call your list when it is fresh, before the data and the interest go cold.
- Book the follow-up before you hang up, every single time.
- Keep your pace up. More quality calls means more opportunities.
50 telemarketing do’s
Ask experienced callers for their golden rules and most would land on the list below. Whether you are new to outbound calling or have been doing it for years, there will be something here worth a fresh look.
Before you pick up the phone
Plan your calls. Know your products, your market, your competitors, and the problems you solve. You do not need to know everything, but you will sound far more confident when you understand why a prospect should give you their time.
Secure a good call list and clean it first. A strong, accurate list is your single biggest asset. Time spent improving data quality before the campaign pays back many times over once you start dialling.
Keep your data fresh. Wastage is a common problem in any campaign. Research your target list properly and source it from reputable suppliers so more of your calls reach the right person.
Set realistic objectives. Results vary enormously and there are countless variables at play. Use historic benchmarks where you can, and set targets that stretch you without setting you up to fail.
Set realistic KPIs. How many calls per hour? How many appointments, over what timeframe? Measure daily and review often, so you can adjust quickly when something needs to change.
Prepare your objection handling. You already know the objections you will hear. Brainstorm them in advance and rehearse your responses, so you are never caught flat-footed. Our guide to objection handling techniques is a useful starting point.
Use a good CRM. A well-designed workflow lets you find and trigger follow-ups in seconds. The better your system, the more results you will see.
Use technology to speed things up. Click-to-dial, number recognition, and AI-assisted research all help you spend more time talking and less time on admin.
Check your line is clear. With so much calling now over VoIP, a crisp connection matters. Glitches and delays break the flow and undermine your credibility.
Brief your agency properly if you outsource. Weak briefings lead to weak results. You do not need a technical spec, but your agency must understand the real benefits and why prospects need what you offer.
Have a pen and paper ready. You will not remember everything, especially the small details outside your main reason for calling. Good notes give you a head start on the next conversation.
Have your diary open and ready. Fumbling for dates while a busy prospect waits rarely ends well. Be ready to offer times the moment they say yes.
Have a relevant email ready to send. Some prospects respond better to something in writing first. Clarify what they want to see, send it promptly, and agree a time to call back.
Getting through to the decision-maker
Make sure you are calling the right contact. You cannot assume you have the right person every time, so check, politely, that they look after the area you want to discuss.
Stay in control with the gatekeeper. Sound authoritative, keep it short, and remember the gatekeeper can block you but cannot buy from you. Our gatekeeper techniques go deeper on this.
Find a Trojan Horse. Give the prospect a reason to engage, especially if they already have a supplier. What is in it for them? The stronger the pull, the more likely they are to listen.
Call outside normal hours and at lunchtime. The gatekeeper may be away, and hard-to-reach decision-makers often work longer days. Test the water before nine and after five.
Be ready to change your call times. If your usual window is not landing, experiment. A small change in timing can make a real difference to who you reach.
Try to outsmart an IVR. Dialling zero, or calling the accounts line and asking to be put through, can sometimes open a route the front door will not.
Leave enticing voicemails. A bland message gets ignored. If you have to leave one, make it compelling and finish with a clear reason to call you back.
On the call
Ask for what you want. An appointment, a demo, a sale. Make your reason for calling clear early on, without being pushy. Waffling wastes the little time you have.
Be confident. It carries down the line. Expect to succeed and you are far more likely to bring the prospect with you. Confidence persuades, cockiness repels.
Be honest. It really is the best approach, and you will be found out if you are not. Genuine advice, free of over-selling, is surprisingly compelling.
Be motivated. People buy people. If you sound flat and bored, why would anyone want to engage? Your energy sets the tone for the whole call.
Sound authoritative. Aim to sound at least as senior as the person you are speaking to. It is peer to peer, and a nervous, squeaky pitch will not get you past the gatekeeper, let alone the buyer.
Sound professional, with good pace and tone. Match your prospect where you can. Make them feel they are speaking to a credible company with something worth hearing.
Smile. “Smile while you dial” is a cliché for a reason. Your mood travels through your voice, and it shapes how the call goes.
Be passionate about what you offer. You do not need to be relentlessly upbeat, but real belief in the value you bring goes a long way. Anchor it to a problem you genuinely solve.
Talk off script. Few people respond well to an obvious pitch. A call should feel like a conversation, not a presentation. Read more on talking about customer needs.
Use natural, engaging language. Keep it simple and human. Plain English builds rapport far faster than corporate speak.
Use evocative, compelling words. Words like significant, dramatic, and substantial add impact when they fit. Just do not overdo it.
Assume the outcome and ask for it. Approach the call expecting a yes and ask with that quiet assumption in mind. Belief in yourself is powerful.
Questioning, listening and rapport
Ask great questions. Open questions get prospects talking and giving you information. Closed questions qualify and filter. Blend the two so it never feels like an interrogation.
Listen carefully. Two ears, one mouth. Active listening means audible responses that show you are engaged, and replying to what they actually said rather than what you wanted to say.
Read between the lines. Prospects are not always direct. Clarify gently if you sense hesitation, and give them room to be honest with you.
Summarise the conversation. Replay the key points and the prospect’s pains before you recommend anything. It proves you listened and strengthens their reason to engage.
Build rapport. This is the single biggest driver of telemarketing success. People will not give you the time of day if they do not warm to you. See our rapport-building techniques.
Use frames of reference. Past projects, client names, and industry examples reassure prospects that you understand their world and can be trusted to deliver.
Use feel, felt, found. This well-known technique builds empathy, and empathy supports rapport, which in turn lifts your results. Pair it with good open questions.
Treat people how they want to be treated. Consider their motivations and pressures. If they are busy, recognise it, empathise, and lock in a better time to talk.
After the call
Follow up, on time, every time. Weak follow-up is one of the biggest reasons sales are lost. Make sure your system triggers call-backs exactly when you promised them.
Agree on a time to call back. Even a no for now can become a yes later. That pipeline of future interest is gold dust, so ask for the next step at the end of every call.
Take good notes. Capture verbatim comments, tone, and personality, not just the facts. It also lets a colleague pick up the thread if you are unavailable.
Send timely information and confirmations. Strike while the iron is hot. Once the call ends, your prospect has a hundred other priorities competing for attention.
Use the phone to follow up on other marketing. Call the people who opened your emails, connected on LinkedIn, or visited your stand. Outbound calling amplifies everything else you do, and the quicker you act, the better the result.
Mindset and momentum
Be patient. Rejection is part of the job and not everyone is ready to buy at the same time. Keep building your pipeline and the sales will follow.
Make the calls, do not delay. Inertia is your worst enemy. Your prospects are not waiting for you to find the perfect moment, so pick up the phone.
Keep up the pace. Momentum matters. Avoid long gaps between calls, keep water or coffee within reach, and let the volume of quality calls work in your favour.
Change your pitch if it is not working. Treat your call like a good story, with a strong opening, a compelling middle, and a clear ending. If a pattern of nos appears, try a different approach.
Role-play or record your calls. Listening back, alone or with colleagues, is one of the best ways to improve. Regular reviews turn small tweaks into big gains.

50 telemarketing don’ts
Now the flip side. Some of these are simply the opposite of the do’s above, while others are the small habits that quietly sink otherwise good calls. Read them with your last few calls in mind.
Before you dial
Do not forget to keep it legal. Screen your numbers against the TPS and CTPS at least every 28 days, as the rules require. Compliance protects your brand as much as it keeps you on the right side of the law.
Do not keep your team in the dark. Make sure callers are armed with responses to common objections and clear reasons a prospect should meet you now. Working in isolation rarely ends well.
Do not pitch something you do not understand. You will be found out. Go back to your briefing and get to grips with the real benefits before you pick up the phone.
Do not call unprepared for objections. You know the knockbacks are coming. Practise your responses so you are never stuck for an answer.
Do not over-research before every call. Digging into each company is tempting, but doing it for every dial when you might only reach one or two people an hour will wreck your call rate.
Do not set yourself up to fail. Give yourself targets you can hit and exceed. If unrealistic goals have been set for you, raise it early rather than grinding away demotivated.
Getting through
Do not apologise for calling. You are not sorry, and the prospect knows it. Make your point and avoid sounding insincere from the off.
Do not befriend the gatekeeper too early. Their job is to block you, and the more you share, the more they can probe. Keep your eyes on the decision-maker.
Do not stalk someone you cannot reach. Persistent nuisance calling gets remembered, earns your company a bad name, and gets you blocked faster.
Do not wait for ages on hold. Your call rate is your friend. If you are going nowhere, hang up politely and try again later.
Mind your manners
Do not eat while calling. Chomping and slurping down the line is grim. Nobody wants to hear it.
Do not smoke on a call. You may think no one can tell, but smokers know what you are doing and non-smokers will assume you are a heavy breather.
Do not type loudly while listening. The tapping is distracting and tells the prospect you are only half there, even when you are taking helpful notes.
Do not keep your mobile on. You will be tempted to glance at it, and the prospect will sense your attention drifting.
Do not get distracted by anything else. Texts, emails, colleagues, social media. Focus is essential for good calls, although never ignore a fire alarm.
Do not call from a noisy background. It can sound like a call centre, which is rarely the impression you want. A noise-cancelling headset is a cheap fix.
Do not slam the phone down. Even after a rude prospect, stay calm and professional. Hanging up in a huff only damages your brand.
Do not swear. Profanity is a fast track to a dial tone. You might think it sounds confident, but it simply sounds unprofessional.
How you sound and what you say
Do not sound bored or uninterested. If you are flat, your prospect will be too. Rejection is draining, but letting it show only makes things worse.
Do not speak too quickly. Rushing makes you sound nervous and junior. Be energetic by all means, but use questions to even out the pace.
Do not rush the call. Slow down. You will sound more confident, and a well-paced conversation lands far better than a garbled one.
Do not um and er. The odd pause is fine and even useful. Sounding lost for words is not. Know roughly what you want to say and relax.
Do not open with “how are you today”. It is the classic tell of a sales call and marks you out as poorly trained. Drop it.
Do not overcomplicate the call. Keep it simple. Your product knowledge may be fascinating to you, but a busy prospect just needs you to get to the point.
Do not over-script. Stilted, robotic calls get cut short. A script should support you, not read you.
Do not waffle. Be concise. The odd anecdote can engage, but rambling rarely does. Brevity wins.
Do not use jargon you do not understand. The prospect will assume you are an expert and reply in kind, leaving you scrambling.
Do not force humour. The prospect is not your mate and they are busy. Stories and anecdotes can work, but read the room. Relevance is everything.
Do not use slang or pet names. Love, pet, darling, and sweetie all sound unprofessional. Even if the prospect uses such language, do not follow suit unless it is truly natural for you.
Do not overuse the prospect’s name. Dropping it into every sentence sounds like a tacky hard sell. Use it sparingly so it feels genuine.
Do not patronise anyone. Talking down to a gatekeeper or prospect, however irritating they may be, only pushes them towards your competitors.
Questioning, listening and honesty
Do not be afraid to challenge objections. It is a two-way conversation, so engage with genuine, well-informed discussion rather than agreeing for the sake of it. Our questioning techniques can help.
Do not interrupt. Cutting in signals you are not really listening. Whatever the temptation, let them finish.
Do not talk over your prospect. An even conversation flow builds rapport and lifts your chances of a good outcome.
Do not be rude or dismissive. Brushing aside valid points gets you nowhere. Empathy persuades, even when you disagree.
Do not make assumptions. Even seasoned sellers fall into the trap of thinking every prospect shares the same needs. Ask questions and avoid the know-it-all routine.
Do not prejudge a call. You never know what is going on in the background. Every prospect is at a different stage, however strong your offer.
Do not underestimate mirroring. Subtly reflecting a prospect’s language, without parroting, helps you build rapport and earn their ear.
Do not lie. You will be found out, and it will damage your brand. If you do not know something, say so and promise to find out.
Do not guess. There is nothing wrong with not having an answer. Clarify the question, find the answer, and call them back.
Do not forget to ask if it is relevant to others. Even if it is not for your contact, there may well be a need in another department.
Closing and following up
Do not be afraid to ask for the sale. Plenty of callers meander to the end and leave things hanging. If it has been a good call, ask for what you want.
Do not promise what you cannot deliver. Whether it is the product or simply a call-back time, broken promises cost you trust. Keep your word, and you stand out.
Do not bully a prospect into a meeting. Push too hard, and the meeting is more likely to collapse. Your sales colleagues will not thank you, so qualify properly and book good appointments.
Do not argue with a decision-maker. Some people will not see the value, however obvious it seems. Stay gracious and move on rather than getting frustrated.
Do not forget to follow up when you said you would. It is the death knell for sales. So many opportunities are lost to nothing more than poor process. Follow up on the minute you promised.
Mindset
Do not be afraid to change your approach. Not every method works, and not every prospect buys. When a negative pattern appears, adapt.
Do not sit back and wait for the phone to ring. Be proactive. If prospects are not beating a path to your door, go and find them.
Do not worry about failure. Before the call, you had no appointment. If they say no, you are exactly where you started. Nothing is lost, so do not let the fear of rejection hold you back.
Do not be afraid to invest in training. If experience or results are lacking, a telemarketing training course is one of the quickest ways to improve. Bite the bullet.
The do’s and don’ts at a glance
If you remember nothing else, remember these five pairings. They are the habits that separate the callers who book meetings from the ones who get hung up on.
| Do this | Avoid this |
| Lead with your reason for calling | Open with “how are you today” |
| Listen at least as much as you talk | Interrupt or talk over the prospect |
| Call your data while it is fresh | Let your list and the interest go cold |
| Book the next step before you hang up | Forget to follow up when you said you would |
| Keep your pace and momentum up | Sit back and wait for the phone to ring |
Putting it all together
Great outbound calling comes down to a blend of preparation, genuine interest, and momentum. We can all spot a poorly trained caller in seconds. They blunder on, talk at you, and care little about the person on the other end. Old-school, scripted, pushy calling is finished. The callers who win in 2026 prepare well, listen hard, sound human, and follow up without fail.
