Best practices for SMS via email

For highest delivery, keep messages simple and text-only. Include one short link to your full ad page.

  • Stay under ~160 characters when possible; avoid attachments.
  • Use clear opt-in language; include easy opt-out instructions.
  • Route image-rich content to your landing page (like this one).
Tip: MMS with images is best handled by dedicated SMS APIs. Our email-to-SMS flow prioritizes text deliverability.
