WhatsApp prospecting: rules, etiquette and message templates

When is WhatsApp the right channel?

In many countries, including Tunisia and the rest of North Africa, WhatsApp is a real work tool: people send quotes on it, confirm meetings, talk to suppliers. A small-business owner will often answer a WhatsApp faster than an email. That’s exactly why it needs care.

What WhatsApp’s rules say

The WhatsApp Business Messaging Policy (checked in October 2026) is clear on three points:

• Consent: you may only contact people on WhatsApp if they gave you their number and opted in to receive your messages or calls. It’s up to you to collect that opt-in in a way that complies with applicable law.
• Opt-out: you must respect every request, on or off WhatsApp, to block, stop or opt out of your messages, including removing the person from your contact list.
• Quality: users can block or report a business, and WhatsApp may limit how many messages a business can send based on that feedback.

On top of that, each country’s data-protection and direct-marketing law applies (GDPR for contacts in Europe, Organic Law No. 2004-63 in Tunisia, for example). This guide isn’t legal advice; when in doubt, get advice.

WhatsApp etiquette for B2B

• Introduce yourself in the first line: first name, company, and where you spoke. Your number probably isn’t saved on their phone.
• One message, not five: put everything in one short message rather than a burst of bubbles.
• No unsolicited voice notes: many people can’t listen at the office. Offer one if the conversation calls for it.
• Business hours: weekdays, during the recipient’s working hours. Keep weekends and periods like Ramadan in mind, when schedules shift.
• Language: reply in the other person’s language. In Tunisia, French, Arabic and Derja often mix; follow their register.
• One follow-up at most: if there’s no reply, one follow-up a few days later, then stop or switch channel.
• An easy way out: simply offer to stop (“just tell me if it’s not the right time, I won’t follow up”).
• Use WhatsApp Business: a business profile with name, description, hours and website is reassuring and keeps work chats apart from your personal account.

10 WhatsApp prospecting message templates

All of these assume the person gave you their number or agreed to talk on WhatsApp. Replace the bracketed parts and shorten where you can.

1. After a phone call

“Hi [First name], it’s [Your name] from [Company], we just spoke on the phone. As agreed, here’s the 2-page overview on [topic]. I’ll call you back on [day] as planned; in the meantime, feel free to ask anything.”

2. After meeting at a trade show or event

“Hi [First name], [Your name] from [Company], we talked yesterday at [event] about [topic]. You mentioned [specific point]: would you have 20 minutes on [day] or [day] to go through it?”

3. After a LinkedIn conversation

“Hi [First name], thanks for your reply on LinkedIn and for your number. Here are the two examples I mentioned for [type of company]. Tell me which one is closest to your situation.”

4. When you’ve been asked for a quote

“Hi [First name], here’s the quote for [service], as requested this morning. It covers [item 1] and [item 2] and is valid until [date]. Happy to adjust it if needed.”

5. Meeting confirmation

“Hi [First name], confirming our meeting on [day] at [time] [at your office / on video: link]. If the time no longer works, let me know and we’ll find another.”

6. Follow-up on a quote with no reply

“Hi [First name], just checking in about the quote I sent on [date]. Have you had a chance to look at it? If the timing isn’t right, no problem at all, just let me know.”

7. Referral from a mutual contact

“Hi [First name], [Contact’s name] gave me your number and said you’d be fine with me writing. I’m [Your name] from [Company]; we help [type of company] [result]. Would you have 15 minutes this week?”

8. After an email the person replied to

“Hi [First name], following your email, I’m writing here as you suggested. Here’s the 3-minute demo video; happy to talk it through whenever suits you this week.”

9. Reconnecting with a former client

“Hi [First name], [Your name] from [Company], we worked together on [project] in [year]. We’re launching [new offer], which could help with [need]. Shall I tell you more?”

10. Closing the loop

“Hi [First name], I don’t want to clutter your WhatsApp, so I’ll close this on my side. If [problem] becomes a priority again, you know where to find me. All the best!”

Fitting WhatsApp into a multichannel sequence

WhatsApp works best as the second or third step: after an accepted LinkedIn invitation, a call or an email reply. A typical sequence: profile visit, LinkedIn invitation, LinkedIn message once accepted, email if there’s no reply, then WhatsApp for prospects who agreed to it. Full examples are in 5 multichannel sequence examples.

In Yalors, the WhatsApp step sits in the same visual builder as LinkedIn and email, with conditions (for example “has a phone”, “replied”), variables with fallbacks, sending windows, random delays and an automatic stop as soon as the prospect replies. Replies land in a unified inbox where an AI copilot flags the intent and drafts an answer in the prospect’s language. Consent stays your responsibility: only put contacts who agreed to WhatsApp into a WhatsApp step.

Mistakes that get your number blocked

• Adding strangers to a “promotions” WhatsApp group.
• Sending the same broadcast to hundreds of numbers found online.
• Ignoring a “stop”, a “no thanks” or a long silence.
• Messaging someone you don’t know in the evening or at the weekend.
• Sending a long text, three images and a voice note before any reply.
• Placing a WhatsApp voice or video call without prior agreement: WhatsApp’s policy also requires opt-in for calls.
