Verify the pattern before you send
Start with the format that appears most often. For Achs, that means testing {f}{last}@achs.cl 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 Achs email format is {f}{last}@achs.cl (for example jdoe@achs.cl), used in about 99% of observed Achs work addresses. Achs also uses 3 other formats for name collisions.
