10 Free Onboarding Email Templates, Tested in 21 Clients
Onboarding mail is the first thing a new account receives, which makes it the most-opened and least-forgiving message a product sends. These templates carry one call to action each, because a welcome that offers three next steps reliably gets none of them clicked.










Why onboarding mail breaks differently
Best of these 10 scores 94 out of 100 across 21 clients, and all of them bottom out in Outlook Classic at 67. Last verified against engine data from that date.
The failure mode in onboarding is almost never visual. It is a button that stops being clickable outside its text, or a verification link rewritten by a security scanner into something the reader will not trust. Both survive a screenshot review and both cost you the activation, which is why the per-client table on each page below matters more than the preview image above it.
Scores are computed by the Emailens engine from per-client support data derived from caniemail.com (MIT).
