What this means for the bank

The checker's own notes on each record:

MX, pass: 2 MX records. Replies have somewhere to land.
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: about 1 of the 10 allowed. This count is an estimate.
DMARC, pass: Policy p=reject: receivers are asked to refuse mail that fails.
DMARC, info: Reports go to fb769ced@inbox.ondmarc.com.
DKIM, info: No DKIM key at the 10 common selectors tried. That does not mean DKIM is missing. Your email provider picks the selector name, and DNS has no way to list them.

What this means if you sell to Glacier Bank

Glacier Bank routes inbound mail through Proofpoint, a filtering gateway. Expect strict inbound filtering: a message from a sender whose SPF, DKIM or DMARC fails, or whose domain has little sending history, is unlikely to reach a person. 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.
