Questions about SendGrid

What format is SendGrid Inbound Parse?

SendGrid Inbound Parse posts incoming mail as multipart/form-data fields, which your app must reassemble. There's no parsed JSON option.

SendGrid vs MailKite for inbound?

MailKite POSTs one parsed JSON object instead of multipart fields, never charges per domain, and needs no sending bundle to receive. See /alternatives/sendgrid-inbound-parse.

Is SendGrid free?

SendGrid has a limited free tier (100 emails/day). Higher features require paid plans.
