SMTP for SendGrid – YaySMTP

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 · 92% 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.

   We host websites on a server that limits the number of files (INODES) we can place in it. I recently replaced an obsolete SendGrid plugin with another, and suddenly I was hitting 85% of my INODE allotment because the new plugin had too many files. I had two options: migrate some of the sites to another server or switch to a lighter plugin. I chose the latter option: “SMTP for SendGrid – YaySMTP” fits my needs perfectly.
