/faq

Things people ask before signing up.

Do I need an AWS account?
No — that's the point. We run the SES infrastructure, the IAM policies, the sending quotas and the region failover. You get an SMTP host and a credential pair.
What happens if I exceed my tier?
Sends over your monthly quota get a polite 452 4.2.2 monthly quota exceeded at MAIL FROM — your mailer's retry logic treats it as temporary. Upgrade any time and the limit lifts immediately. We never silently bill overage.
Do you support dedicated IPs?
On Pro as an optional add-on, and standard on Enterprise with warmed pools. Shared pools are fine for most transactional volume — we keep them clean aggressively.
Is SMTP really all you do?
Sending, yes. SMTP first because every language already speaks it; a REST send API and delivery webhooks are on the Pro roadmap. No marketing-blast tooling, ever.
What about inbound email?
We don't receive mail. justsmtp is send-only by design — no MX records, no mailbox hosting, no forwarding.
Can I cancel anytime?
Yes. Downgrade to Hobby and keep sending your first 1,000 a month free, or delete the account — your DNS records are yours to remove.
