Frequently Asked Questions
Why verify before sending?
High bounce rates damage your sender reputation and push future emails to spam. Cleaning the list first protects your domains.
Do you also verify lists we did not buy from you?
Yes. You can send any list, from any source, and we will clean it.
Does verification guarantee inbox placement?
No service can guarantee that. Verification removes a major cause of problems, but deliverability also depends on your setup, copy and sending habits.
