Right provider, right mailbox, always
Automatic detection of Gmail, Outlook, Yahoo, Apple, and custom providers through domain lookup and MX analysis.
In auto mode, SendKit routes each email through a sender on the same provider as the recipient.
Disabled, auto, or custom rules with priority. Pick the level of control that fits your workflow.
Same-provider delivery improves the chances of landing in primary instead of spam or promotions.
Auto-match providers to mailboxes
Domain lookup and MX record analysis determine whether your lead uses Gmail, Outlook, Yahoo, Apple, or a custom provider.
If the lead is on Gmail, SendKit sends from one of your Gmail mailboxes. Outlook leads get Outlook senders. This improves inbox placement.
Three modes: disabled (no matching), auto (SendKit handles it), or custom rules with priority settings for fine-grained control.
Gmail to Gmail delivery tends to land in primary more often. ESP matching routes your Gmail leads through Gmail senders automatically.
When you have both Gmail and Outlook mailboxes, ESP matching assigns each lead to the best sender. You don't have to think about it.
For advanced setups, define custom rules with priority. Route specific domains through specific mailboxes with full control.
