When should I send a message?

Timing is everything in SMS and MMS marketing. Whether you're sending promotional offers, reminders, or customer updates, knowing when to send your messages can dramatically improve open rates, engagement, and conversions.

In this guide, we’ll break down the best times to send SMS and MMS campaigns through Cellcast — backed by industry benchmarks and behavioural data — so your messages land at the right moment for your audience.

Why Timing Matters for SMS and MMS

SMS has a 98% open rate, and most messages are read within 3 minutes of delivery. But sending a message at the wrong time — like late at night or during a work rush — can hurt your results or even cause opt-outs.

Sending your message when your customer is most likely to engage, click, or act is key to success.
