SMTP2GO for WordPress – Email Made Easy

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 · 68% 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 declining trend compresses what a buyer would pay.

   Cannot use the plugin with php 8.3, shows critical error. Use another plugin. Update: yes it was my issue, allow_url_fopen was disabled in php version on the server for some reason. This topic was modified 11 months, 2 weeks ago by Hal Sclater.

   SMTP has been the bane of my marketing existence forever. I’ve never had such a smooth onboarding. I decided to try it out on my client’s site (loveyourchainlink.com) just to see — since default WordPress emails are tragically and historically a problem. I’m pretty sure it just took 2 minutes. I’m going to put this on my own site and another client site, too. Wow! Thank you!

   It works like a charm, is so easy to set up compared to the old authentication method, and is lightweight. I highly recommend this gem, and I’m very happy that I found it. I will get a plan when I reach my usage. Please keep the free plan. Big thanks!  This topic was modified 1 year, 2 months ago by WPuser.

   It’s the official plugin of the best email sending service out there. The setup is ultra simplified. Forget about messing with DNS, SMTP server, ports. Once you’ve done with your account on their site, it just works fast and reliable out-of-the-box. A step ahead.

   I’ve tried a number of SMTP tools for transactional emails for various sites I have built. SMTP2Go is by far the easiest to set up. I had some issues with one site and their tech support team responded quickly and solved the problem in 5 minutes. There is no waiting for “approval,” no credit cards required for the free account, and setting up CNAME records is a snap. I won’t go back to any other SMTP plugin. Thank you!
