Reach the inbox without tricks.
Google and Microsoft reward real senders: clean lists, correct DNS, steady volume and real replies. We build all four into the product.
A slow start for every new mailbox.
A brand-new mailbox that sends 200 emails on day one looks like spam. Ours start at 10 a day and grow over three weeks. Already warmed up elsewhere? Skip it with one tick.
Every address checked on upload.
- Domains that can't receive emailOften a typo, like gmial.com. Never imported.
- Throwaway inboxesTemporary addresses nobody reads. Never imported.
- Team addressesinfo@, sales@ and similar. Few replies, more spam reports. Left out unless you ask.
- Duplicates and blocked addressesMerged or skipped, including anyone who unsubscribed or bounced before.
We also detect who hosts each inbox: Google Workspace, Gmail, Microsoft 365, Outlook.com, Zoho, Yahoo, and over 25 others such as Proofpoint, Mimecast and GoDaddy.
Safety nets that act on their own.
Domain and server checks, every day
SPF (including the 10-lookup limit), 2048-bit DKIM, DMARC policy, MX and domain age for every domain. Spamhaus blocklists for every domain and SMTP server, plus reverse DNS. Each problem comes with a plain fix.
Bounce limits
A campaign pauses at its bounce limit. A mailbox pauses at 8% hard bounces. A spike holds all sending for 24 hours.
Provider pauses
If Zoho, Gmail or Microsoft asks to slow down, the mailbox pauses and resumes on its own, instead of failing.
One-click unsubscribe
The List-Unsubscribe header Google and Yahoo require, plus an optional line or link in the email.
Account-wide blocklist
Unsubscribes and hard bounces are blocked in every workspace, for good.
Sensible daily caps
Up to 200 a day per mailbox, with 30 to 50 recommended. Send more by adding mailboxes.
Status for every mailbox, at a glance.
Health, sent today, DNS badges, slow-start progress and provider pauses, on one page.
