What this means for the bank

The checker's own notes on each record:

MX, pass: 1 MX record. Replies have somewhere to land. Mail is handled by Microsoft 365.
SPF, pass: One SPF record, ending in ~all (softfail): mail from a server that is not on the list is treated as suspect.
SPF, info: DNS lookups: at least 7 of the 10 allowed. This count is an estimate.
SPF, info: The record uses SPF macros, which only resolve for a real message, so the lookup count is a floor.
DMARC, pass: Policy p=reject: receivers are asked to refuse mail that fails.
DMARC, info: Reports go to dbcadcb6@inbox.ondmarc.com.
DKIM, pass: DKIM key found at selector1._domainkey.amerisbank.com, about 1024-bit RSA.
DKIM, pass: DKIM key found at selector2._domainkey.amerisbank.com, about 2048-bit RSA.
DKIM, pass: DKIM key found at s1._domainkey.amerisbank.com, about 2048-bit RSA.
DKIM, pass: DKIM key found at s2._domainkey.amerisbank.com, about 2048-bit RSA.

What this means if you sell to Ameris Bank

Ameris Bank receives mail through Microsoft 365, whose Exchange Online Protection checks every inbound message's SPF, DKIM and DMARC and scores the sender's reputation. A clean, warmed sending domain is the minimum; a failed check lands in junk or is dropped. Before you send, run your own domain through the email setup checker and publish a policy with the DMARC record generator. For how a bank buys, see the selling to banks playbook.
