Your email is going to reach the inbox, not spam

Technical guidance, built-in tools and our own infrastructure so SPF, DKIM, DMARC and reputation work in your favor. No magic promises — deliverability is built with data, not marketing.

The 3 pillars

What deliverability rests on

Three areas work in parallel. Neglect one and it drags the other two down.

Authentication

The receiving server verifies that the email really comes from you and wasn't altered. The SPF + DKIM + DMARC triad.

Reputation

Your domain and IP build up a track record. The better the engagement, the better the delivery. You protect it with consistent practices.

Warmup

Operational hygiene

Clean lists, managed bounces, monitored complaints. Without this, not even the best authentication can save you.

How your identity gets verified

Three checks between your send and the inbox

Every time you send, the receiving server queries your domain's DNS and runs three checks in milliseconds. If all three pass, your email lands in the main inbox.

We don't resell a generic SMTP. aMailMTA delivers your emails while protecting your reputation with three mechanisms that run on their own in the background.

Traffic shaping

Sending profiles per provider (Gmail, Outlook, Yahoo) that respect each ISP's limits.

Automatic backoff

If it detects rejections, it automatically slows down sending speed to avoid burning reputation.

IP warmup

Gradual warmup of new IPs to build reputation progressively and safely.

And 5 of our own SMTP servers behind it

Every server with SPF, DKIM and constant reputation monitoring. We spot problems before you do.

Dedicated infrastructure

Our own SMTP servers, separated by send type. An outage on one doesn't compromise the rest.

End-to-end authentication

SPF, DKIM and DMARC assisted from the dashboard. We tell you exactly what to publish and validate it once it propagates.

Monitored reputation

Google Postmaster, Microsoft SNDS and our own cross-checked reports. Early alerts if anything shifts.

The 5 nodes sending on your behalf

Each account operates against a subset of servers assigned by reputation and traffic type.

Optional add-on · Deliverability

Your sending IP,
yours alone.

Add a dedicated SMTP server with an exclusive public IP for your account's sender. Your sending reputation stops depending on anyone else's behavior: you build it and you keep it. It's optional and can be added to any plan.

Shared IP

The starting point, with no infrastructure cost: your campaigns go out through the same IP as other customers, with a reputation already built and managed by arrobaMail. The catch is that this reputation is collective.

Dedicated server with exclusive IP

A public IP that sends only your email. Your reputation is independent from the shared IP and from anyone else's behavior: what Gmail, Outlook and Yahoo see is your track record and nothing else.

When is it worth it?

It's optional and never mandatory, but we strongly recommend it if you send on a regular basis: plans of 100,000 monthly sends or more, any unlimited plan (you can move a lot of volume even with a small list) and reseller operations, where it also isolates each client's risk.

Frequently asked questions

What people ask most about deliverability

Deliverability is the discipline that explains why an email reaches the inbox, lands in spam or gets rejected. Improving it has a direct impact on opens, clicks and results: good design isn't enough if the message doesn't arrive well.

With SPF. It's the simplest and most basic. Then DKIM. Then DMARC at p=none to monitor. And in parallel, if your domain is new, a 4-week warmup plan.

Not necessarily. SPF, DKIM and DMARC are published in your domain's DNS once and that's it. arrobaMail assists every step from the dashboard. What you do need is access to your domain's DNS (managed at your provider: Cloudflare, GoDaddy, Route53, etc.).

To control the reputation of the IPs, separate traffic by type (transactional vs marketing) and avoid depending on third-party relays. Our servers (envios, s1, s2, s3, full) run on our own infrastructure with SPF, DKIM and constant reputation monitoring.

No. Nobody can honestly promise "100% inbox". What we can offer is infrastructure, tools and assistance aligned with best practices: our own servers, assisted authentication, domain diagnostics, guided warmup and real-time reports.
