One workspace, one Stripe subscription, the full deliverability + identity-verification stack. Anomaly detection + mailbox verification + authentication checks at the core; inbox placement / warmup / phone / blacklist on the edges. Click into any feature for a full breakdown of what's included during your Trial, how it pairs with the others, and the live per-action cost.
One coupled action per signup — cluster bot waves, score risk, and confirm the mailbox actually receives mail.
Bot waves rarely reuse an address twice — they lean on plus-addressing, dotted Gmail variants and disposable domains. Clustering catches the shared pattern that per-address email verification misses on its own.
SPF · DKIM · DMARC · MX — scored, cached, surfaced on every record.
A sender's authentication posture predicts whether mail reaches the inbox at all. Every address you check returns the domain's SPF, DKIM, DMARC and MX state, cached so repeat lookups cost nothing.
See where your mail lands across Gmail / Yahoo / Outlook.
Delivered is not the same as seen. Seed-inbox tests across the major providers show whether a campaign lands in Primary, Promotions or spam — before it goes out to a real list.
Auto-warm every sending mailbox you sell from — 1 mailbox or 50.
A cold domain gets throttled or filtered for weeks. Warmup builds sending reputation on a schedule across a pooled network, per mailbox, so new senders ramp without daily babysitting.
Catch VoIP & toll-free before they pollute your SMS campaigns.
VoIP and toll-free numbers pass a format check but fail on delivery. E.164 normalisation plus carrier lookup separates reachable mobile numbers from the rest before you pay to message them.
50+ industry blacklists on every domain — before deliverability bites.
By the time open rates drop you have usually been listed for days. Checking 50+ RBLs on every domain and sending IP surfaces a listing while it's still cheap to get delisted.
