What You Can Do¶
Collect Subscribers¶
Add subscribers from your app via the Swift SDK, CSV import, or the REST API. Organize them with tags and segments to target the right people with the right message.
Write and Send Campaigns¶
Compose emails using MJML, personalize with template variables, and target by tag or segment. Preview and test before sending, then schedule or send immediately.
Automate Your Email¶
Set up a welcome series to greet new subscribers automatically, or build drip sequences that deliver content over days and weeks. MailJawn handles timing, enrollment, and exit conditions.
Track What Works¶
See campaign reports with opens, clicks, and bounces. Dive into subscriber activity for individual engagement history. Learn what your metrics mean and how to improve them.
Protect Your Reputation¶
Configure custom sending domains, understand bounce handling, and stay compliant with email regulations. MailJawn monitors your deliverability health and warns you before problems escalate.
