your IP. your inbox.
nobody else’s name on it.

adbtd runs full email infrastructure on bare metal. your own SMTP, IMAP, and a virgin dedicated IP under your domain. recipients see you. we don’t appear in the headers, the DNS, or the conversation. ten minutes, terminal to inbox.

why adbtd

email infrastructure is supposed to be invisible. ours actually is.

most “providers” leave fingerprints. their domain in your headers, their IP under your sending, their reputation tied to your inbox. adbtd doesn’t.

01 / pristine

virgin IP, only yours

fresh dedicated IP per account. never shared, never recycled, never pre-warmed by someone else's traffic. you start at zero. the right zero.

02 / unbranded

no adbtd in the headers

SPF, DKIM, return-path, MX. all aligned to your domain. no via sender.io, no third-party signers, no reseller giveaways.

your IP, your rules

cold outreach, transactional, list ops. what you do is your business. we provision, we monitor, we don't gate your sends. burn it and that's on you.

architecture

bare metal. your own MTA. nothing shared.

other providers serve thousands of customers from one set of binaries. when one tenant gets compromised, blacklisted, or rate-limited, you feel it. adbtd ships you your own stack.

typical resellershared

one fleet, every customer multiplexed in. one bad actor poisons the well. your IP, their reputation.

adbtdsingle-tenant

your own container, your own postfix + dovecot + rspamd, your own IP, your own DNS namespace. compromise stops at your door. there's no door to anyone else's.

what you get

nine things every cold-outreach team already wishes they had.

bare metal, no cloud

physical servers we operate. no AWS/GCP markup, no shared hypervisor, no surprise provider outage cascading through five customers.

full whitemark

your domain in every header, your DNS, your DKIM signer. recipients can't tell adbtd exists. clients can't either, unless you tell them.

10 / 10 across rankers

mail-tester, GlockApps, MXToolbox, ISNotSpam, DKIMValidator. all 10/10 out of the box. SPF, DKIM, DMARC, MTA-STS, TLS-RPT, BIMI all configured day one.

up & running in minutes

account → order → live. typical end-to-end is around a minute once your DNS resolves. point a domain you already own at us and you're sending today.

virgin IPs, never tainted

every IP we hand out is fresh from the upstream allocator, RBL-checked before issuance. not pre-warmed, not pre-burned, not shared. nobody knows it exists yet.

no send limits

you manage your own reputation. send 10 / day or 100k. burn the IP and that's on you. we'll tell you when bounce rates climb, but we won't gate the spigot.

affordable at scale

$1.99 / mailbox, $19 / dedicated IP. that's the whole menu. 240 mailboxes + 3 IPs = $534/mo. compare that to anyone else.

true single-tenant

your own postfix, dovecot, rspamd containers. not shared binaries, not shared DBs. another customer's RCE, blacklist, or backlog cannot touch you.

API & agent-ready

everything in the dashboard is also in the API. provision, send, fetch, automate from the terminal or from an LLM. designed for agents, not just humans.

api & automation

spawn infra in seconds, from your terminal.

every dashboard action has a JSON-API equivalent. AI agents and scripts get the same primitives. order mailboxes, send, read inboxes, rotate IPs. authentication is one bearer token; rate limits are honest; the docs ship with curl.

  • provisionPOST domains, IPs, mailboxes.
  • sendPOST a message, we hand it to your tenant SMTP. no central queue.
  • readGET listings & individual messages over IMAP-via-REST. paged by UID.
  • automatebuilt so an agent loop reads, replies, escalates, all from one key.

deliverability

your reputation, watched on five fronts.

we score every outbound message, audit your DNS every six hours, probe public RBLs, and pull verdicts from Google & Microsoft directly. when the needle moves, you see it before the receiver does.

score every outbound, block what’s spammy

avg · 7d · 1.42

our anti-spam engine scores each outgoing message on the same scale receivers use. you decide whether messages above a threshold also get rejected at SMTP submission, so a bad copy never goes out under your name.
