Mailrelay

74 Quality Score

Active Installs

14/30

With only 1,000 active installs, this is a niche plugin with limited reach compared to mainstream alternatives, which pulls the popularity score down despite a small boost from use-case breadth.

Update Freshness

25/25

The plugin was last updated on August 7, 2025, and is tested against WordPress 6.8.5, which signals an actively maintained codebase, though a null PHP requirement is a minor transparency gap.

User Rating

13/15

An 84 out of 100 from 5 ratings is a solid score but comes from a very small sample, so the rating should be read with caution rather than treated as a broad consensus.

Support Health

8/15

With zero support threads opened and zero resolved, there is no real track record to judge responsiveness, and the 0.0 percent resolution rate reflects an empty queue rather than poor service.

WP Compatibility

15/15

The plugin requires WordPress 5.0 and has been tested with 6.8.5, covering a wide range of sites, although the lack of a stated PHP version is a small compatibility red flag.

What It Does

Mailrelay connects your WordPress user database to Mailrelay.com, automatically syncing registrations, profile updates, and unsubscribes with your email marketing account. It lets you segment users by WordPress role and push them into Mailrelay groups without manual CSV imports. The plugin focuses on the bridge between your site and Mailrelay, not on sending or designing emails itself.

Who It's For

This plugin is a good fit for small businesses, bloggers, and membership site owners in the Spanish-speaking world who already use or are committed to Mailrelay.com as their email service provider. It is most useful for sites where WordPress user roles map directly to newsletter segments, such as membership tiers or customer types. If you run a course platform or community with a clear subscriber hierarchy, the role-based syncing is a practical asset.

Who Should Skip It

If you are not already using Mailrelay.com, there is little reason to start with this plugin given the stronger, more popular alternatives available. Anyone needing built-in email design, automation, or analytics tools should look at a full email marketing suite like MailPoet or Mailchimp for WordPress instead.

The Bottom Line

Mailrelay does one thing, syncing WordPress users to Mailrelay.com, and it does it with a recent update and decent user ratings, but its tiny install base and lack of any support history make it a hard plugin to recommend broadly. It earns a 62.44 out of 100 quality score, which places it firmly in the cautious-use category. Choose it only if Mailrelay.com is your locked-in email platform; otherwise, the alternatives above offer more features and a stronger community.

Pick this if you are a Hostinger customer who wants AI-assisted email creation, automation, and a one-click signup form without configuring a third-party service.

MC4WP: Mailchimp for WordPress 89/100

Pick this if you already use Mailchimp and need a mature, well-supported integration with deep form, list, and tagging options.

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

Pick this if you want to send and design emails directly from WordPress without depending on an external email service provider.

Newsletter – Send awesome emails from WordPress 85/100

Pick this if you want a self-contained newsletter plugin with a large install base and strong documentation, rather than just a sync bridge to another service.

Newsletters, Email Marketing, SMS and Popups by Omnisend 84/100

Pick this if you need ecommerce-focused email and SMS automation, especially if you run a WooCommerce store.
