Written once, personalised for everyone.
First name, city, any column of your file: each subscriber gets their own version. You stack blocks — text, image, button — and Mailcheer handles the rest: who gets it, which domain it leaves from, and what comes back.

No subscribers yet? Everyone starts from zero. Add your first contacts one by one, importing can wait — and your contacts are never billed.
Reach the right people, without sorting by hand.
Segments are built in two clicks and recalculate on their own: new signups, customers, inactive. You choose who receives, Mailcheer handles the rest.
Click a segment: the count updates.
Land in the inbox, not in spam.
Your emails go out in your name (@your-company.com), authenticated — that's what Gmail and Outlook check before filing them. Mailcheer gives you the exact values to publish at your DNS host, then checks they're in place.

From an empty account to the inbox.
Here is exactly what awaits you, step by step — from an empty account to the first email read.
Account created in two minutes without a card, contacts imported, domain authenticated: Mailcheer gives you the SPF, DKIM and DMARC values, then checks them.
Blocks to stack — text, image, button. No HTML. AI suggests your subject line and rewrites your paragraphs.
A segment in two clicks, a test to your own inbox, a checklist that verifies everything — then off it goes, or scheduled.
Opens and clicks on every email, tracked by default — campaigns and API sends alike. Bounces, unsubscribes, your sender reputation in plain sight, and a list that cleans itself.
Want to try it yourself?
Open the software with real data, without creating an account.

Type your website's name: in two seconds you know whether your sends risk the spam folder, and what's missing to avoid it.
Here is what's new this month, plus the offer reserved for our customers…
- SPF — the sender is allowed
- DKIM — the message is signed
- DMARC — the policy is published
Without these three records, Gmail and Outlook can't tell it's really you. When in doubt, they file it as spam.
A fair price that follows your volume.
