This site is made by the team at Resend. It deliberately runs no forms and no JavaScript, so there is nothing to submit here—but the humans behind it are easy to reach.
Challenge a verdict or suggest a question
If you think an answer is wrong, incomplete, or missing a question you keep hearing, we genuinely want to know. Reach the team through resend.com/contact or on X at @resend. Mention doineed.email and the answer you're writing about.
Help with your own sending
Questions about your own deliverability, domain setup, or email infrastructure belong with Resend support—the team includes deliverability experts with decades of combined experience, and that's a better place for specifics than any general-purpose answer on this site.
