Preflight reduces avoidable problems. It cannot promise inbox placement. Your sending domain, audience permission, list health, and message still matter.
Send yourself a test
After Preflight, choose Send Test Email in the same health bar. Open the message on devices you use, click important links, and check the sender name and reply address. Test emails use Migma’s sender, so you can review a draft before adding your own sending domain.Next
