Skip the gatekeepers
SendKit can detect when a recipient's domain is protected by a Secure Email Gateway. Skip SEG-protected leads entirely or route them through specific mailboxes for better handling.

Dodge spam filters before you send
SendKit identifies Secure Email Gateways before you send so you're not going in blind.
Automatically exclude SEG-protected leads from campaigns if you don't want to deal with the deliverability risk.
Send to SEG-protected domains through designated mailboxes with different sending patterns.
By handling SEG leads separately, your overall campaign metrics stay accurate.
Catch spam flags before you hit send
Before sending, SendKit checks whether the recipient's domain is protected by a Secure Email Gateway.
Two options: skip SEG-protected leads automatically, or route them through specific mailboxes you designate for SEG handling.
SEG-protected domains are harder to land in. By detecting them upfront, you avoid wasting sends and protect your deliverability metrics.
Enterprise companies often use SEGs. Detect them before sending and decide whether to skip or route through specialized mailboxes.
SEG-protected domains have higher bounce and spam rates. Skipping them or handling them separately keeps your overall metrics clean.
Route SEG leads through specific mailboxes with warmer reputations or different sending patterns to improve your chances.
Proactive detection, not post-mortem
Know about SEGs before you hit send
Most cold email tools send blindly and let you figure out why deliverability dropped. SendKit detects Secure Email Gateways on recipient domains so you can skip those leads or route them through specific mailboxes.
Skip or route. Your choice.
When a SEG is detected on a recipient's domain, you have two options: skip the lead entirely (they won't receive any emails from this campaign) or route them through specific mailboxes you designate for SEG handling.
