Suspended? Breathe. Then do these in order.

You searched this mid-crisis, so here's the page in one line: secure your data, appeal calmly, fix the cause before you move — and know that we screen senders too, so this is a triage guide, not a back door.

Why platforms suspend senders

Almost every suspension traces to one of five things: a spike in spam complaints, a spike in bounces (usually an old or purchased list meeting reality), a policy sweep over a content category, a compromised key or form quietly blasting spam from your account, or — sometimes — a false positive. Suspensions are what a platform's abuse systems do to protect the reputation every one of its senders shares. We know because we run the same kind of screening: every outbound message is machine-screened for abuse — spam, scams, phishing, brand impersonation, and malware links — at admission and again at send, on every self-serve plan; the screen is automated and runs before delivery, never a person reading your mail.

None of that makes the day less bad. Here is the order of operations.

First: secure what's yours

1. Export your contact list, with its fields, while the dashboard still lets you.
2. Export your unsubscribe and bounce lists. These stay binding wherever you send next — losing them is how you re-email people who already said no.
3. Export your templates and note the DNS records the platform had you set.
4. Write down the timeline — when sending stopped, what the notice said, what changed in the days before. You'll want it for any appeal, theirs or anyone's.

Second: appeal like a professional

Appeals written in fury lose. Say what you send, to whom, where the list came from, what changed before the suspension, and what you've already fixed. If the platform publishes an acceptable-use policy, read it before replying — the appeal that shows you understand the rule works better than the one that argues the rule is wrong.

Third: audit before you re-send anywhere

Be more honest with yourself than the appeal requires. Where did every segment of the list come from? When did each address last engage? Is there a purchased or scraped block in there from years ago? A suspension is often the first hard data a sender gets about a list problem — use it, because the problem travels with the list, not the platform.

Where we stand — said plainly

We'd like your business, and we screen for the same things that got you suspended. Both halves of that sentence are true:

• Early access is application-gated — every application is read by a person, and what we ask is public: a real sending domain, an opted-in audience, honest answers.
• Consent is infrastructure here, not paperwork: hosted signup forms with double opt-in through our own delivery path, so every subscriber carries verifiable proof of consent.
• Imports are screened. Garbage and throwaway addresses never enter a list, we ask where the list came from, and outsized imports can be held for a human decision before they land.
• Sending ramps deliberately — Email Fast runs its own mail transfer agent, warmup engine, reputation breaker, and per-tenant fair queue — we run these ourselves, with no upstream ESP reselling us your delivery.

So, plainly: if your list was purchased, we will decline — the acceptable use policy is not a formality. If you were a false positive, bring the facts; the review is human, and it's fast. We make no promises of acceptance, and a platform that would is telling you what its other customers look like.

If you're moving anyway

Provider-specific switch guides, each honest about what ports and what doesn't: SendGrid · Mailgun · Postmark · EmailJS · Mailchimp · beehiiv · Substack

And when you're ready: apply for early access — migration help is part of onboarding, and the sandbox proves your pipeline before anything real sends: sandbox keys (ef_sandbox_…) that run the real pipeline dry: real validation, real rendering, real events, a hosted capture inbox — and no email leaves.
