SMTP for SendGrid – YaySMTP

67 Quality Score

Active Installs

14/30

With only 1,000 active installs and a top-end cap of 45/30 on popularity, the plugin has a small user base compared to mainstream SMTP plugins that routinely exceed 100,000 installs.

Update Freshness

25/25

Maintenance scores the maximum 100/25, reflecting an update as recent as May 2026 and clearly active development by the YayCommerce team.

User Rating

6/15

Ratings score 40/15, pulled down by having only two user reviews, which is far too small a sample to draw meaningful conclusions about reliability or satisfaction.

Support Health

8/15

Support health sits at 50/15 because there are zero public support threads and zero resolved tickets, giving no evidence either way of how the developer responds when users run into trouble.

WP Compatibility

15/15

Compatibility hits the full 100/15, claiming support for WordPress 7.0 and PHP 5.3, although the very low PHP floor is a practical concern for modern stacks.

What It Does

SMTP for SendGrid by YayCommerce routes WordPress outgoing email through SendGrid's SMTP servers instead of the default PHP mail function, improving deliverability for transactional messages like order confirmations, password resets, and notifications. It is a focused, single-provider connector: no multi-provider failover, no built-in logging, and no analytics layer beyond what SendGrid itself offers.

Who It's For

Best suited for site owners who already use SendGrid as their transactional email provider and want a lightweight, no-frills SMTP connector without paying for a premium mailer plugin. Small businesses running WooCommerce stores, membership sites, or form-driven lead generation pages that need reliable delivery and already trust SendGrid will get the most value.

Who Should Skip It

Anyone using a different email provider, or anyone who needs email logs, open and click tracking, multi-provider fallback, or detailed reporting should skip this plugin and choose a more capable option like YaySMTP, WP Mail SMTP, or Post SMTP. It is also a poor fit for high-volume senders who require batching or queue management features that this plugin does not appear to provide.

The Bottom Line

SMTP for SendGrid by YayCommerce is a lean, actively maintained connector that does one thing reasonably well, but its tiny install count (1,000), thin rating base (2 reviews), and absence of public support history make it hard to recommend over YaySMTP's own flagship plugin or GoSMTP. It is a reasonable pick only if you specifically want a minimal SendGrid-only solution and do not need logs, tracking, or multi-provider fallback. Overall Quality Score: 66.93/100.
