What this means for the bank

The checker's own notes on each record:

MX, pass: 1 MX record. Replies have somewhere to land.
SPF, pass: One SPF record, ending in -all (fail): mail from a server that is not on the list should be rejected.
SPF, info: DNS lookups: at least 9 of the 10 allowed. One more sending service could push it over. 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 dmarc-reporting@suttonbank.com.
DKIM, pass: DKIM key found at s1._domainkey.suttonbank.com, about 1024-bit RSA.

What this means if you sell to Sutton Bank

Sutton Bank's MX hosts belong to a provider we do not name from host names alone. Assume the inbound server checks SPF, DKIM and DMARC and scores reputation, as every major provider does. 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.
