Hi {{first_name|there}},
Every week I try the tools people send me and keep only what earns its place. This week, three made the cut.

The subscriber tax
Every list has readers who stopped opening. Per-subscriber pricing charges you for each one, every month, and keeps mailing them, which drags your emails toward spam for everyone else.
01Readers who go quiet get one last email: “Still want this?”
02No answer, no more issues. They stay on your list, never deleted, and cost you nothing.
03Your opens go up, your spam rate goes down. On by default.
The product
Everything a newsletter needs, with nothing to configure before your first issue.

Subject, preview text, unsubscribe link, Gmail's 100 KB clip, postal address and sender, checked for you.
See the issue in a phone inbox, with a real reader's name and fields filled in.
Start with your most engaged readers, then send to more from the report.
Every issue gets an SEO-ready page at you.lowsend.com or your own domain.
Opens and clicks hour by hour, by inbox provider, against your last 10 issues.
AI agents
Every button in the dashboard is a tool in our MCP server and an endpoint in the REST API, with the same checks and limits. Your agent writes, tests, schedules and reports. It asks you before anything goes out.
Done. “Field Notes #43” is in your inbox as a test and goes out Sunday at 9:00 AM. Want me to send it now instead?
Deliverability
Five safeguards run on every send, on by default. Each account sends on its own, so nobody else's mistakes land on you.
Typos like gmial.com, spam traps, throwaway inboxes and dead domains are left out of imports and signups.
DKIM, SPF and DMARC on every email. On your own domain, we hand you the records and check each one.
5% first. The rest follows 3 hours later, only if bounces and complaints stay low.
A send pauses past 2% bounces or 0.08% spam complaints, before your reputation pays for it.
Readers who stopped opening get a “still want this?” email, then stop getting issues.
Switching
Bring your list as it is, from wherever it lives today.
Download the CSV from your current platform. Any of the ones on the left.
We read its columns, statuses, signup dates and tags, and leave out the bad addresses.
Unsubscribed and bounced readers stay out. The rest get your issue, from your domain or ours.

Your emails are authenticated with DKIM, SPF and DMARC. New senders start slow and earn their speed with clean sends, new contacts get a small first batch, and readers who stopped opening get one last email before they stop getting issues. A send pauses on its own if too many emails bounce or get marked as spam.
Because sending is what costs money; storing a subscriber costs almost nothing. Per-subscriber pricing makes you pay for people who stopped reading, and keeping them hurts your deliverability. lowsend cleans them out by default and doesn't charge you for them.
Connect lowsend in ChatGPT, Claude or Grok with your sign-in, or add it to Claude Code, Cursor or Codex with an API key. Your agent can write drafts, send you tests, schedule issues and read your stats. Sending to your list can't be undone, so your agent asks you first.
Yes. Export your subscribers as a CSV and import it on the Contacts page. lowsend reads each platform's columns and statuses, keeps signup dates, and leaves out duplicates, invalid addresses and people who unsubscribed.
No. You can send from hello@your-newsletter.lowsend.com, with your website at your-newsletter.lowsend.com. Add your own domain anytime and your emails move to it.
Signups keep working and confirmation emails still go out. New sends wait until you upgrade or your next month starts. Once the month's emails are used up, welcome emails pause too.
No. Plans start at $19 a month and you can cancel anytime.
Yes, from the billing page. Your plan keeps working until the end of the period you paid for. Your data stays, and everything comes back if you subscribe again.
From $19 a month for 20,000 emails. Every feature, every plan.
