Mailster Mailgun Integration

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 · 98% 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.

   Every time I switch over to mailgun plugin I get Cron Lock. All parameter have to be so low that it’s hopeless to use this. I have to set the number of email to 20 and 150ms between each and then is’s working for 2 or 3 cycles. I use cron job on siteground to run the job and this is configured to run every 30 min. So my newsletter use 2-3 weeks to get out. I never gets cron lock when using simple smtp.

   This plugin have some serious flaw, I tried everything using this plug in, it won’t complete my email delivery list. This error kept on appearing: ‘to’ parameter is not a valid address. please check documentation. The worst of it, it doesn’t have email log funchtion, so I could not know what went wrong, I suspect it was a bug in the software, using Post SMTP Mailer/Email Log solved all of my problems and it also had email log function, If there is any errors in the future, I could easily track it.

   I have tried this plugin, and set everything right in Mailgun itself. I was keep getting the following error: ‘to’ parameter is not a valid address. please check documentation. While searching long for as solution, I tried WP SMTP, and the error was gone and my campaign was sending again.
