Biggest opportunity: Swap “delivery”, “email” and “smtp” for “dkim”, “resolve” and “spf”. “delivery” isn't earning its slot: you're not in the first 24 results for its own search. “dkim” sits at #4 untagged, close enough for a declared tag to move it up. “email” isn't earning its slot: you're not in the first 24 results for its own search. “resolve” sits at #4 untagged, close enough for a declared tag to move it up. “smtp” isn't earning its slot: you're not in the first 24 results for its own search. “spf” sits at #5 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

How it's measured →9.1%
of downloads still active
At least 40K of 437.5K lifetime downloads are still running, above its category: the median Email & Marketing plugin keeps 0.9%, across 1,296 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Email & Marketing plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
This plugin shipped 5 releases in the last 12 months, and every existing install that updated counted as another download. wp.org publishes no split between first installs and updates, so we show the raw rate rather than guess at one.

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.

Whatever your email volume, this plugin will meet your needs. I’m on the free plan and the support was still remarkable.

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!
