WHEN DOES IT MAKE SENSE TO SWITCH FROM JUST SMTP?

Pricing has outgrown your usage
If your usage of Just SMTP has crossed a pricing-tier breakpoint, per-unit cost is usually where alternatives diverge most clearly.

Yoast SEO – Advanced SEO with real-time guidance and built-in AISupport response has slowed you down
Support quality is the hardest thing to read from a listing, and it is the most common reason a switch gets made. Read the most RECENT reviews on each alternative's profile rather than the lifetime average — recency is what tells you how the app is supported today, and trailing review velocity is the freshest signal AppRanks tracks.
