Mailster AmazonSES Integration

52 Quality Score

Active Installs

14/30

About 2,000 active installs is modest and shows a niche audience limited to existing Mailster users who also want SES, but the score is boosted slightly above raw install count.

Update Freshness

8/25

Last updated on 2025-03-26 and tested against WordPress 6.8.5, which is current, though the maintenance history shows only one developer managing a small integration rather than a larger team.

User Rating

12/15

A perfect 100 from 4 reviews is statistically thin, so the high score should be read as 'nobody has complained yet' rather than strong validated satisfaction.

Support Health

8/15

Only 1 support thread exists with 0% resolved, which is a meaningful red flag given how AWS credential and sandbox issues typically need guided support.

WP Compatibility

11/15

Requires WordPress 6.0+ and PHP 7.4+, which is reasonable and broad, and the recent WordPress 6.8.5 test stamp suggests current compatibility.

What It Does

Mailster AmazonSES Integration connects the Mailster Newsletter plugin to Amazon Simple Email Service, routing outgoing newsletter and campaign emails through SES rather than a generic WordPress wp_mail transport. It handles the SMTP/API handshake with AWS and passes Mailster's queued messages through SES for delivery, which is useful for sites already using AWS or those needing higher sending limits than typical shared hosts allow.

Who It's For

This plugin is for site owners who already use (or plan to use) Mailster for newsletters and need Amazon SES as their delivery backend, typically because they send high volume, want lower per-email costs, or operate inside the AWS ecosystem. It fits agencies, e-commerce shops, SaaS platforms, and nonprofits that have outgrown standard hosting SMTP and need SES's scale.

Who Should Skip It

If you do not already run Mailster as your newsletter plugin, this add-on is useless, and you would be better served by a full newsletter plugin with its own ESP integration. Anyone sending low volume who is happy with their current delivery should also skip it: SES requires AWS account setup, IAM permissions, and sandbox verification that is overkill for small lists.

The Bottom Line

Mailster AmazonSES Integration scores 57.1/100, reflecting a small but actively maintained bridge plugin that does one specific job for a narrow audience. It is a sensible pick if you already use Mailster and want SES as your delivery layer, but the unresolved support thread and tiny user base mean you should be comfortable troubleshooting AWS issues on your own. Everyone else should look at a full newsletter plugin first.

Pick this if you want an all-in-one newsletter solution with built-in sending and AI features rather than wiring Mailster to an external ESP.

MC4WP: Mailchimp for WordPress 89/100

Choose this if your delivery backend is Mailchimp and you want signup forms, lists, and integrations handled in one plugin.

MailPoet – Newsletters, Email Marketing, and Automation 89/100

Choose this if you want a self-contained newsletter plugin that sends through its own infrastructure or your own SMTP without needing Mailster at all.

Newsletter – Send awesome emails from WordPress 85/100

Pick this if you want a free, broadly supported newsletter plugin and would rather route SES through a generic SMTP setting than a Mailster-specific addon.

Advanced Ads – Ad Manager & AdSense 85/100

This is a different category, but if you landed here looking for monetization tools, it is the more relevant option for ad revenue rather than email delivery.
