Choosing between email, SMS and WhatsApp

Email is included and suits detail, SMS costs per message and suits urgency and consent should cover the channel you use.

Campaigns can go by email, SMS or WhatsApp. Email is included in your plan. Text and WhatsApp messages carry a per-message cost, so use them where the immediacy is worth paying for.

Email

Best for anything with detail, images or more than one idea. Cheap enough to send regularly, easy to ignore, and it can carry a proper offer with a link.

SMS

Almost always read, and read within minutes. That makes it right for genuine urgency, like a cancellation you want filled this afternoon. It also makes it intrusive if you use it for a newsletter.

WhatsApp

Sits between the two. More room than a text and more conversational, but it is a personal space and people notice when a business turns up in it uninvited.

The rule of thumb

Would you be pleased to receive this by text? If the honest answer is that an email would have done, send the email.

Cost control

Watch what you are spending on messaging. Settings, then Messaging, is where your messaging arrangement lives.

Common questions

Do I need separate consent for SMS?

Consent should cover the channel you use. Somebody who agreed to emails has not necessarily agreed to texts, and the safest position is to be specific when you ask.

Which gets the best response?

SMS gets read most, email gets acted on most for anything needing thought. Use them for different jobs rather than picking a winner.

What happens if I run out of messaging credit?

Sends stop rather than silently failing. Check Settings, then Messaging, to see where you stand.
