Tried the two primary alternatives & found that they simply didn't work insofar yahoo mail flatly rejects emails originating from them. SMTP2Go worked flawlessly. Initial free pricing structure nicely matches my starting need. Support is swift & thorough, which is also a nice contrast to certain alternatives. Recommended.

After trying a number of other SMTP plugins, SMTP2GO has by far been the easiest to set up. It is truly a set and forget solution where once it's configured, you can sit back and expect everything to run smoothly! I just wish I stumbled across it sooner.

I'm very happy with SMTP2Go. I've been using it for a few months after my previous SMTP provider started having deliverability issues. Not having any problems now, SMTP2Go is super easy to set up as well, and the WP plugin makes everything seamless. Highly recommend.

I have been using SMPT2GO for about 3 months now. I used to have emails rejected by Gmail and Yahoo customers due to my servers IP address, which was very frustrating. SMPT2GO integrated seamlessly with my Woocommerce site, and with my local Thunderbird email client. Since using SMPT2GO, all of my emails reach my customers, and I now have a very low bounce rate. I would highly recommend SMPT2GO.

I always want to buid or test WordPress websites on my personal Windows IIS local host environment. But sending emails is not easy or not possible. Sometimes the Internet provider is blocking the SMTP port 25 and/or others. But with SMTP2GO WordPress plugin is working very good and fast. So SMTP2GO WordPress plugin gives solutions for everyone and everywhere. Simply the best SMTP plugin ever!

Finally a plugin for an external mail relay that just works out of the box, have used other mail relays over the years and never managed to get a WP plugin to work with them correctly however SMTP2GO have nailed it and it works flawlessly
