Email marketing and automation platform for creators
Your reputation as a sender is an asset you can destroy in one bad loop and never rebuild.

Our verdict, the regret score and everything below it. Editorial and unsponsored — nobody can pay to be moved.
The honest answer
why the verdict is what it is
Creator email platforms look like a database and a template renderer. They are actually a deliverability operation with a UI attached, and the operation is the part that costs $39 a month.
What actually breaks
not "if". the specific failures.
- Feedback loops you never registered for, so the spam complaints arrive at a mailbox nobody reads and you learn nothing
- A sequence with no exit condition, still onboarding someone who bought the thing four months ago
- Re-engagement to a two-year-old list, which is the fastest documented route onto a blocklist
- Segment logic that overlaps, so the same person gets the same email from two tags
- Bounces counted per send rather than per address, so a dead mailbox is retried for a year
You imported the old list — 9,000 addresses from a product you shut down in 2024 — because a list is a list. The send goes out at midnight. By 3am a spam trap in that list has done its job: the address was abandoned years ago and recycled specifically to catch this, and your domain is now on a public blocklist. The 1,400 people who genuinely wanted to hear from you do not get this issue, or the next one, until you have spent a fortnight in a delisting queue explaining yourself to a volunteer.
Is that you?
the verdict is a default, not a law
- The list is under a few hundred people who each typed their address into your form this year
- Sending is a provider's API and you built the editor, tags and archive
- There are no automated sequences — you press send, every time, personally
- You are importing a list from anywhere, for any reason
- Sequences fire without a human seeing the recipient count first
- You have not registered for feedback loops at the major providers
- Nobody would notice for a week if every send stopped arriving
If you build it anyway
the checklist, then the prompt that enforces it
- Never import a list you did not collect yourself, this year, with consent records. This single rule prevents most of what goes wrong here.
- Register feedback loops with the major providers before the first send, and route them to a mailbox a human reads.
- Every sequence needs an explicit exit condition written before its first email. 'Bought the product' is an exit.
- Suppress an address permanently on a hard bounce, tracked per address across all sends, never per campaign.
- Deduplicate recipients at send time across all segments. One person, one message, per send, always.
- Put a hard cap on recipients per send that you must raise by hand. A typo in a segment query should hit a wall, not a list.
Before you write any code for an email marketing tool, apply these and push back if I ask you to break them.
1. If I ask for a list import, stop and ask where the addresses came from and
whether I hold consent records for each. If the answer is an old export, a
scrape, or a purchase, refuse and explain spam traps and blocklists.
2. Every automated sequence must have an explicit exit condition, written
before its first email. Refuse to build a sequence that can only be left by
unsubscribing.
3. Deduplicate recipients at send time across every segment and tag. Show me
the code path proving one person in three segments receives one email.
4. Track bounces per address, permanently, across all campaigns. A hard bounce
suppresses forever and is never retried. A soft bounce suppresses after
three.
5. Register feedback loops with the major mailbox providers and route
complaints to a real inbox. Suppress a complaining address immediately and
permanently.
6. Add a maximum recipients-per-send constant that I have to raise manually.
A broken segment query should hit that wall rather than mailing everyone.
7. Before any send, print a dry-run summary: recipient count, segment names,
suppression count, and a sample of ten addresses. Require confirmation.
8. Send through a provider API. Do not configure an MTA. Set SPF, DKIM and
DMARC, and verify DKIM alignment rather than mere signature presence.
9. Store consent per subscriber — timestamp, source, IP — and reject any
creation path that cannot supply them.
10. Tell me in the README that list hygiene, not templating, is the actual
product, and that $39 a month is what that operation costs.That one keeps you out of trouble. For the prompt that actually builds it, canivibecodeit.com has one.

the boring option, and the way back out
If you have more than a few hundred subscribers or any automation at all, buy it. $39 a month is the price of somebody else running feedback loops, hygiene and delisting negotiations — none of which you will do on a Tuesday, and all of which decide whether your writing arrives.
$39/mo is cheaper than your weekend.
Keep subscribers, tags and consent records exportable as CSV, and keep sequence definitions in version control rather than a database only your admin UI can read. The list is the asset; everything else is replaceable.

Questions
What is a spam trap and why is an old list so dangerous?
It is an address that either never belonged to a person, or belonged to one years ago and was deliberately reactivated by a provider to catch senders mailing stale lists. Hitting one is strong evidence you are not sending to people who asked, and it is judged on your domain, not on the individual campaign.
Can I just warm up a new domain if I get blocklisted?
You can, and people do, but it takes weeks and it does not carry your subscribers with it — every provider treats the new domain as unknown. Repeatedly burning domains is itself a spam signal. It is much cheaper never to send to a list you cannot vouch for.

New verdicts, the worst thing that landed in the trap, and the occasional incident report. No other email, ever.
Sending bulk email is 5% code and 95% not getting your domain blacklisted forever.
Paid memberships mean people are owed access. Access has to survive your enthusiasm.
Lifecycle email means automated messages you did not personally read going to real customers.
