Bit SMTP – Easy SMTP Solution with Email Logs

74 Quality Score

Active Installs

15/30

With roughly 2,000 active installs, Bit SMTP is a niche plugin rather than a mainstream choice, which keeps its popularity score modest.

Update Freshness

25/25

Last updated May 2026 and tested against WordPress 6.9.4, the plugin is clearly being actively maintained by its developers.

User Rating

12/15

A 78 out of 100 rating from 15 users is reasonable but based on a small sample, so the signal is limited.

Support Health

8/15

Zero support threads with zero resolutions is a yellow flag: there is no public track record of the author helping users who run into trouble.

WP Compatibility

15/15

Requires PHP 7.4 and WordPress 5.0, which is compatible with virtually every modern WordPress environment and earns a perfect compatibility score.

What It Does

Bit SMTP replaces WordPress's default PHP mail function with authenticated SMTP delivery, letting you route outgoing site emails through providers such as Gmail, Outlook, SendGrid, Brevo, Mailgun, and Amazon SES. It also stores an email log so you can review what was sent, when, and whether delivery succeeded. Setup is a straightforward credential-entry process aimed at non-technical users.

Who It's For

This plugin fits small businesses, freelancers, and small stores that send transactional emails (order receipts, contact form replies, booking confirmations) and want a simple SMTP replacement without the overhead of a larger plugin. It is a sensible choice for sites on modest hosting where a lightweight, low-config option is preferred over a feature-heavy platform.

Who Should Skip It

Sites handling high-volume marketing or transactional email at scale should look elsewhere, and anyone needing premium support, advanced deliverability tooling, or failover routing will find this plugin too thin. If you require responsive developer help or integrations beyond basic SMTP, the alternatives below are stronger fits.

The Bottom Line

Bit SMTP does the basics competently and is clearly maintained, but the absence of any support history and its tiny install base make it a hard sell over WP Mail SMTP, FluentSMTP, or Post SMTP. It is fine for a simple site that just needs SMTP and email logs, but I would not recommend it for mission-critical email workflows. Score 73.98 out of 100.
