SendGrid alternatives,
compared
SendGrid is one of the oldest email APIs. Teams leave over plan pricing, a dashboard that has grown complex, and support that is hard to reach on smaller plans.
Why teams look beyond SendGrid
Tiered plans
You pay for a monthly volume tier, used or not, with separate marketing plans.
Complex to run
Years of features make setup and the dashboard heavier than newer tools.
Closed source
You cannot read the code or run it on your own servers.
