Verify the pattern before you send
Start with the format that appears most often. For Arquitecto, that means testing {f}{last}@coac.net first, then verifying the exact address before it reaches your CRM or sequencer. A pattern can be common and still produce bad guesses when a person uses a nickname, a middle initial, a regional mailbox, or an older alias.
VeriMails checks syntax, MX records, SMTP behavior, disposable domains, and catch-all detection so you can keep valid addresses and skip risky ones. For larger files, credits start at $19 for 10,000 verifications and never expire. Create a free account, test the pattern on a few addresses, then buy more credits only when you need volume. Run the check again before a large campaign if the list is old, because domains change mail routing and people leave.
The most common Arquitecto email format is {f}{last}@coac.net (for example jdoe@coac.net), used in about 29% of observed Arquitecto work addresses. Arquitecto also uses 7 other formats for name collisions.
