100 email toutes les 5 Mn
The limitation of the amount of emails per batch is not related to SendGrid but with your server.
You’ll need to start with 100 emails each 5 minutes and if you notice that it’s handling well, then you can increase it.
Make sure you have the checkbox “web API” checked under the hostname of SendGrid on the Send With tab, okay?!
Let me know how it goes!
