SAR Friendly SMTP

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Share of active installs on each version of this plugin · 99% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from.

   I used to use PostMan SMTP – now Post SMTP plugin, but this has become very annoying. Because it has become a bulky plugin that almost forces you to go to a paid subscription. The Post SMTP zip file is 8,7MB, while this SAR Friendly SMTP is only 38kB! Of course the other plugin has many more options, but if you just need the mail to be sent by SMTP this SAR Friendly SMTP plugin is absolutely fabulous. Therefore I just made a small donation.

   We tried Postmark. We tried Post SMTP. They would either not deliver e-mails at all (via a SendGrid API relay)… or would only relay text versions. With this plugin, it just WORKED. Thank you!

   This is just what it needs to be. A few settings, a simple easy way to proof them OK and just care for your server or hosting has everything in place, as the plugin works just great. ¡Gracias Samuel!

   It probably works fine, but I uninstalled it immediately after activating it because it clutters up the admin menu with a new top-level item, even though you only interact with it once.

   This is one of the most efficient plugins we use for every site build. Today I had a need for smtp on a multisite network and wanted the same account for all sites. I almost spent $200 on commercial, premium plugin but looked at the SAR Friendly SMTP documentation to find I can add the settings as constants in wp-config.php. Game changer. I’m very happy to continue using this plugin with this multisite install. For the record, I’m a supporter of many premium plugins and spend 4 figures a year on just plugin renewals. But, why add more complexity and cost when it’s not needed?
