The 3 numbers we watch every week
Growth is a boring habit
Hi friend - this week we shipped less, and the list grew anyway. Here is what we changed.
- · One issue, one idea, one link.
- · A subject line you would open yourself.
- · A list you would be happy to keep.

Deliverability
Built to land in the inbox
The unglamorous work that decides whether anyone reads your issue. It is on by default, on every plan, and it does not need a plugin.
Authenticated sending
SPF, DKIM and DMARC records, with a guided check for each one.
One-click unsubscribe
A signed unsubscribe link and header on every email, as Gmail and Yahoo require.
Sending limits that protect you
A send pauses when hard bounces or complaints climb past a safe threshold.
List cleanup
Readers who stop opening get one last email, then stop receiving issues.
Suppression list
Addresses that bounced, complained or unsubscribed are never emailed again.
No bought lists
Imports leave out invalid, duplicate and known-bad addresses before they land.
AI agents and API
Your AI agent can do everything you can
The dashboard is a client of the API, not a separate product. Same actions, same checks, same limits - whether a person clicks or an agent calls.
ChatGPT
writes your next issue
create_campaignClaude
schedules it for Sunday
schedule_campaignCursor
sends it, once you say yes
send_campaignCodex
tells you how it did
get_campaign_reportGrok
imports your subscribers
import_contactsMCP server
Point your agent at one URL and it gets the same tools as the dashboard.
SetupChatGPT, Claude and Grok connect with your StalkMail sign-in. Claude Code, Cursor and Codex use an API key. Sending is marked as an action that cannot be undone, so your agent asks first.
Why StalkMail
Small, honest, and built for the way people work now
Most email tools grew into suites: a page builder, a CRM, a course platform, a popup engine. Somewhere in there, sending a newsletter got complicated and expensive.
StalkMail does the parts that matter - writing, sending, scheduling, growing a list and understanding what happened - and leaves the rest alone. The interface stays out of the way, and the price stays predictable.
It is also built for a world where more work is done by agents. Every button in the dashboard has an API behind it, so an assistant can do the same job with the same rules. Not a bolt-on, not a beta endpoint. The same product.
- The StalkMail team
Affordable by design
You pay for the emails you send, not for a list that sits still. The price is on the page, with no sales call.
Simple on purpose
If a feature needs a manual, we cut it. The dashboard should be understandable in one sitting.
Agent-first, not agent-added
Every action has an API and an MCP tool, with the same checks as the dashboard. Automation is not a second-class path.
