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: The record hands over to a850pbn4._spf._d.mim.ec with redirect=, so its ending comes from that record.
SPF, info: DNS lookups: about 7 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 10935d82b780261@rep.dmarcanalyzer.com.
DKIM, pass: DKIM key found at selector1._domainkey.fidelitybankonline.com, about 1024-bit RSA.

What this means if you sell to Fidelity Co-operative Bank

Fidelity Co-operative Bank routes inbound mail through Mimecast, 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.
