SMS or email: which channel should an urgent campaign use?

Email is suited to detail; SMS excels when information is short, expected and time-sensitive. Choose according to the objective, not habit.

SMS brings urgency closer

An SMS appears on the device recipients usually carry. In a Twilio survey, the stated average SMS response time was 90 seconds, illustrating the channel's potential for confirmations and short actions.

SMS opens are not measured like email opens. Track delivery, link clicks, replies and final conversions instead.

Email remains valuable for detail

Email offers room for conditions, documents and fuller explanations. Mailchimp places average opens near 34%, with large variations by sector and measurement method.

A coordinated combination often works best: a complete email followed by a concise SMS close to the deadline.

  • Urgent and actionable: SMS
  • Long content or attachment: email
  • Important journey: a coordinated combination
