amgill's review on fluentsmtp
Switching all my client sites over to this one! @amgill

Have been using “the other” SMTP plugin for years and all of a sudden it stopped delivering emails. Moved to Fluent and quickly got emails working again with no issues. Thank you. I am switching all my client sites over to this one!

omariusa's review on fluentsmtp
This plugin is a godsend! @omariusa

I used to work with another SMTP plugin that did not give free access to the logs, It was pretty much useless since not having access to the logs made it very hard to troubleshoot tricky issues during production. Thank you!
