Why it matters
One dirty list can send all your email to spam.
A big list has dead and fake addresses
You send, and many of them bounce
Inbox providers lower your reputation
Your next emails land in spam, not the inbox
SleekVerify checks every address before you send and removes the bad ones, so you only mail real inboxes. Your bounce rate stays low, your reputation stays strong, and your campaigns keep landing where people actually read them.
Lands in spam
High bounces tell inbox providers your list is low quality, so even your good emails get filtered out.
Lands in the inbox
A clean list keeps bounces near zero, protects your reputation, and gets your campaigns delivered.
Two ways to check
Pick how deep you want to go.
DNS Only
The quick check
Confirms the email's provider exists and can accept mail at all, like checking a building exists and has a letterbox without knocking on any one door. Instant, completely safe, and it never risks your sender reputation. A fast first pass over a huge list.
Fast · zero risk · ~50ms
SMTP Deep
The thorough check
Knocks on the exact mailbox to confirm that specific inbox can really receive mail. Catches more dead and fake addresses than the quick check. It is slower and needs a special connection, so it is best saved for your most important lists.
