Your sends stop arriving. No one tells you until the damage is done.
A busy store sends to addresses collected at checkout — fast, often misspelled. Mailcheer catches the dead ones before they hit SES limits, kills a runaway campaign mid-flight, and keeps your domain's reputation intact.
No credit card required
The only dashboard that matters
Your bounce rate isn't a metric, it's a hard limit
Beyond it, it's not the campaign that suffers — it's your account's sending capacity. These four figures are permanently shown on your dashboard.
What Mailcheer handles for you
A dead address never goes out again
A hard bounce unsubscribes the address and adds it to your workspace's suppression list. The next campaign never sees it.
The send stops without waiting for you
If bounces spike mid-campaign, Mailcheer pauses the send on its own. Better a thousand emails stopped than a burned domain.
Your sends go out signed
SPF, DKIM and DMARC, with a step-by-step guide for 14 hosts — Cloudflare, GoDaddy, Namecheap, Ionos and others — including menu paths. Without authentication, a store sending at volume gets classified as spam before it's read. Gmail and Yahoo have required DMARC from bulk senders since 2024, Outlook since 2025.

From your store to Mailcheer
How do my customers get from my store into Mailcheer?
Through your store's customer export, dropped into Mailcheer: email, first name and last name are picked up, duplicates removed, and any address on your suppression list stays unsubscribed. A Mailcheer sign-up form on your site adds new subscribers as they come in, and the public API adds or unsubscribes customers from your own code.
Get your next campaign out clean
The free plan includes 3,000 sends per month, no credit card. Enough to run your first campaign, watch the sender health panel, and see what your bounce rate actually looks like.
