Define the segment in writing

Industry, size band, geography, and the trigger that makes now the right time. If a record does not match all four, it does not belong on the list.

Directories, job boards, review sites, association member lists and public filings all produce companies that generic databases miss.

Every field you collect must appear in the email or in a filter. Everything else is maintenance cost.

Run addresses through verification, drop catch-all and risky results from the first campaign, and keep bounces under two percent.

Unsubscribes, customers, open opportunities and competitors go on a permanent suppression list checked before every import.

Set up your domain, warm your mailboxes and launch a sequence in MunchReach.
