One place for everyone who signs up for anything you make.
Every project you ship — an app, a book, an album — gets its own lists and form endpoints in one dashboard. 10,000 records free, for life. Yours, exportable, always.

Free means 10,000 records. Not per month. For life.
Most form backends give you 50 submissions a month and per-contact pricing forever after. Mail Collectly’s free plan is 10,000 stored records and 10 endpoints across unlimited projects — a lifetime allowance, not a meter that resets. Delete old records and the space is yours again. And when you outgrow us, or just want to leave: export is free, forever, cap or no cap. Your audience is yours. We’ll hold the door.

Sending campaigns is the paid tier — it’s the only thing that costs us real money per unit. Everything about storing and owning your audience is free.

Form backends have the plumbing but no idea what an audience is. Waitlist tools forget you the day you launch. Newsletter platforms assume you have exactly one brand. If you’re a person with an app, a book, and a side project — Mail Collectly is the first tool where that’s the normal case, not a workaround with tags.

When you hit a limit, everything tells you — in plain language.
Most APIs just stop working and let you debug the silence. Every Mail Collectly surface returns the same four facts: what limit, where you stand, what’s safe, what to do. Your dashboard shows it, the API returns it, and if your agent asks over MCP, it hears it in words:
“Your form isn’t broken — you’ve hit your 10,000-record threshold. Delete records or upgrade to resume.”
MCP tool result, verbatim
HTTP/1.1 409 X-Records-Used: 10000 X-Records-Limit: 10000 { "error": "account_over_record_limit", "message": "Collection paused — nothing lost. Delete records or upgrade to resume.", "records_used": 10000, "records_limit": 10000, "dashboard_url": "…/records", "upgrade_url": "…/settings/plan" }
I ship apps, books, and music under one small imprint. Every launch page needed an email form, and every option was someone else’s branding, someone else’s per-contact meter, or a Google Sheet duct-taped to a free forwarder. The duct tape version got my inbox flooded by bots because the free tier’s captcha was off by default. So I built the thing I kept wishing existed: one dashboard for every project’s audience, spam protection that’s on by default, limits that are generous and honest, and an export button that never stops working. I’m user number one, and every endpoint on my own sites runs through it.

Questions worth answering.
What counts as a record?A stored list signup or a stored form submission. The same email on three lists is three records; forwarded-mode form submissions are stored nowhere and count as zero.
What happens when I hit 10,000?Collection pauses with a friendly response; nothing is lost, nothing is locked. Delete records to free space, or upgrade.
Can you hold my data hostage?No. Export is free forever, before, at, and after any limit.
Will you email my subscribers?Never without you pressing send. The free tier sends nothing at all; campaigns are the paid tier, with one-click unsubscribe built in.
Is there spam protection?On by default: rate limits, honeypots, time-traps, domain checks, disposable-address blocking, and optional Turnstile per endpoint.
Is there an API?Yes — everything the dashboard does, plus an MCP server so your coding agent can provision endpoints for you.
