SMTP for Contact Form 7

66 Quality Score

Active Installs

14/30

At 1,000 active installs this is a very niche plugin, well behind mainstream SMTP tools, though it is enough to validate that a small community is using it.

Update Freshness

25/25

Updated June 2026 and tested against WordPress 7.0, indicating the single developer is actively keeping it current.

User Rating

5/15

Only two ratings total producing an 80/100 score, so the rating is essentially anecdotal and not statistically meaningful.

Support Health

8/15

One open support thread with zero resolutions suggests the developer has not yet built a responsive support track record.

WP Compatibility

15/15

Supports WordPress 5.5 and PHP 7.4, which covers the vast majority of self-hosted installs without issues.

What It Does

SMTP for Contact Form 7 reconfigures WordPress's wp_mail() function to send outgoing email through a proper SMTP server, including support for OAuth2 providers. It adds custom email templates and delivers automated reports on form submissions. In practice, it routes all Contact Form 7 notifications, and optionally other site mail, through authenticated delivery channels so messages stop landing in spam.

Who It's For

This plugin suits small businesses, nonprofits, and solo operators who rely heavily on Contact Form 7 and want a single plugin that handles SMTP, OAuth2 authentication, and email logs without paying for a premium SMTP plugin. Sites with low to moderate email volume (under a few hundred form submissions per day) will get the most value.

Who Should Skip It

Anyone not actively using Contact Form 7, or anyone running a high-traffic site with complex multi-provider email routing, should skip this plugin in favour of a general-purpose SMTP solution. Given the tiny install base (1,000) and an unresolved support queue, you should also avoid it if you cannot troubleshoot SMTP and OAuth issues on your own.

The Bottom Line

SMTP for Contact Form 7 packs solid SMTP, OAuth2, and reporting features into a free plugin, but its 1,000 installs and 0% resolved support rate make it a higher-risk bet than the alternatives. It earns a middling Overall Quality Score of 65.73/100, comfortably below every top alternative listed. Use it if you trust the developer and want a CF7-focused tool; otherwise, install WP Mail SMTP or FluentSMTP instead.
