Question 1

Do all SendGrid alternatives support SMTP?

Accepted Answer

No. Some are API-first and skip SMTP. If you need SMTP, choose accordingly.

Question 2

Why do teams look for SendGrid alternatives?

Accepted Answer

Most often: deliverability confidence, pricing changes, support, or wanting a simpler developer experience.

Question 3

What should I choose for pure transactional email?

Accepted Answer

Postmark is a common pick for transactional-first. SES can be cheapest, but requires more setup.

Question 4

Do I need a dedicated IP?

Accepted Answer

Only if you send high volume or need strict reputation control. For many teams, shared IP pools are fine.
