Built-in warmup, blacklist monitoring, and spam analysis run continuously across every sending domain and mailbox — so your agents reach humans, not the spam folder. Deliverability isn't an add-on; it's the foundation.
Every sending domain is protected continuously — reputation built, threats caught, and content scored before a single email goes out.
AI-driven warmup ramps every new domain and mailbox across thousands of warm peers — so you're trusted before you ever send cold.
Continuous DNSBL monitoring across the major lists, with automatic rotation the moment a domain or IP is flagged.
Pre-send scoring against 40+ ESP heuristics — authentication, content, and links checked so you fix problems before you hit send.
Reputation is measured and enforced per mailbox — so one bad address can't drag down the rest, and a flagged domain rotates out automatically.
Each mailbox is warmed and scored on its own — issues stay isolated.
A mailbox that starts bouncing is paused automatically before it hurts the domain.
Sends spread across healthy mailboxes to keep volume natural and within limits.
Hook up Gmail, Outlook, or SMTP — Artra reads your DNS and sets the baseline.
Warmup starts the day you connect, ramping volume to build reputation safely.
Every message is scored against ESP heuristics before it leaves the queue.
Blacklists, bounces, and placement are watched 24/7 — with auto-pause and rotation.
Outbound only works if it arrives. Artra treats deliverability as a first-class system — measured per mailbox, enforced on every send — so your reply rates reflect your message, not your sender reputation.
Free forever tier. No credit card. Warmup starts the day you connect a domain.
