Deliverability

Deliverability that climbs on its own

Every message goes out authenticated, routed across tier-1 networks, and promoted to the highest-deliverability tier your sending earns. You ship features; we keep you landing in the inbox — not spam.

The flight path

Built to land in the inbox, not spam

Authenticated mail rides the string up past SPF, DKIM, and DMARC into the inbox. Flip the toggle to see what happens to mail that isn't.

The upgrade queue

Your reputation moves up, automatically

Deliverability isn't a one-time setup — it's earned over time. MailKite watches how each domain sends and promotes it to the best provider and tier for its pattern. The longer you send clean mail, the higher you climb. Cloudflare and Amazon SES do the carrying; the intelligence on top is what lands your mail.

Nothing to configure. The longer you send clean mail, the higher MailKite promotes your domain.

Best-path routing

Your mail rides Cloudflare, Amazon SES, and other tier-1 networks. MailKite picks the best path for every message — and reroutes if one degrades, so delivery never rides on a single provider.

Automatic promotion

MailKite learns how each domain sends and moves it to the highest-deliverability tier its sending earns. Placement gets better as you go — nothing to configure, no reputation to babysit.

Continuous AI review

As you send, MailKite samples your mail and reads the delivery signals — authentication, routing, timing — and tunes each domain toward the inbox, flagging risk before it costs you.

Pool hygiene

Spam never rides in your lane

On a shared platform, your inbox placement is only as good as the company you keep. MailKite keeps abusive senders on a separate, isolated pool — so the reputation your mail rides stays clean, no matter who else is on the network.

Your domain rides a reputation that abusive senders never share.

The fundamentals

Authentication, handled

The three checks every inbox looks for — configured, signed, and monitored for you.

SPF
Sender Policy Framework

Authorizes MailKite's servers to send for your domain. Receivers check the sending host against your published record — we keep it aligned.

DKIM
DomainKeys Identified Mail

Every message is cryptographically signed with a key on your domain, so receivers can prove it wasn't altered in transit. We publish and rotate the keys.

DMARC
Domain-based Message Authentication

Ties SPF and DKIM to the From: address recipients actually see, and tells inboxes to trust aligned mail. Configured and monitored for you.

Also handled Warmed sending domain Reverse DNS (PTR) TLS in transit Bounce & complaint handling Feedback loops List-Unsubscribe headers

Questions

How does MailKite improve email deliverability over time?

MailKite runs a provider upgrade queue. Every domain starts in a warmed shared pool and, as it builds a clean sending history, is automatically promoted to the highest-deliverability tier its pattern earns — across tier-1 networks like Cloudflare and Amazon SES. Your inbox placement climbs on its own; there's nothing to configure and no reputation to hand-manage.

Does MailKite use shared or dedicated IPs?

Neither is something you have to choose or manage. MailKite routes each message across multiple tier-1 networks and picks the best path per send, promoting your domain to higher-reputation tiers as your sending earns it. You get the deliverability of a well-run dedicated setup without warming or babysitting an IP yourself.

Which networks does MailKite send across?

Your mail rides Cloudflare, Amazon SES, and other tier-1 networks. MailKite chooses the best path for every message and reroutes automatically if a provider degrades, so your delivery never depends on a single sender.

Do I need to set up SPF, DKIM, and DMARC myself?

No. MailKite configures and monitors SPF, DKIM, and DMARC for your domain, publishing and rotating the keys and keeping alignment correct. You add a domain; authentication is handled.

How does MailKite keep other senders' spam from hurting my deliverability?

Abusive senders are kept on a separate, isolated pool that never shares your reputation. Your domain rides a clean lane, so a bad actor elsewhere on the platform can't drag your inbox placement down.

Is there anything to warm up or configure?

No. A warmed sending domain, reverse DNS (PTR), TLS in transit, bounce and complaint handling, feedback loops, and List-Unsubscribe headers are all handled for you. You ship features; MailKite keeps you out of the spam folder.
