Chasing a lead who typed in a fake or mangled email address wastes a follow up before it even starts, and by the time a bounce shows up the best moment to send a text has usually passed. Truelist checks whether an address is real before anyone wastes time on it, flagging disposable domains and dead mailboxes so a bad contact never gets treated like a good one.

You can validate a single email on the spot, create a batch from a longer list, or get an estimate of the cost and time before you commit to running it. Once a batch finishes, download the results as a CSV or pull them back through list emails, so only the addresses that are actually deliverable move forward. Connected to Mobile Message through Zapier, that validation step becomes a gate a lead has to clear before your team sends anything by text.

Pair Truelist with a lead form or a paid order and the checked email becomes the signal a text message is allowed to go out on, so a welcome text or an order confirmation only reaches people whose details actually stack up, and a batch you meant to delete never gets acted on by mistake.
