Email deliverability for fintech
Where the addresses come from
- Account sign-up, where the address is checked as part of onboarding and identity checks.
- Application flows that were started and abandoned, which carry addresses entered under pressure.
- Partner and referral channels, with a weaker consent story and more variable quality.
- Business customer contacts, which behave like an ordinary B2B list with a higher standard of care.
Somebody is faking you right now
Financial brands are the most spoofed targets in email. Without a DMARC policy at quarantine or reject, anyone can put your exact domain in a From header and receiving servers have no instruction to refuse it.
That turns sender checks from a delivery improvement into a customer protection measure. The reason to reach p=reject here is not inbox placement, it is that your customers receive fraudulent mail wearing your name.
Security alerts add urgency on the other side. A login alert or a suspicious transaction alert that lands in junk is a security control that silently failed, and the customer finds out from their balance.
What the results tend to look like
Consumer-weighted for retail products and business-weighted for business ones. Addresses captured during onboarding resolve unusually well, because ID checks tend to produce careful data entry. Abandoned applications are the weak spot.
What to do about it
Get DMARC enforced, rather than merely published
p=none collects data and stops nothing. Quarantine or reject is the only state that prevents exact-domain spoofing, and reaching it is the work.
Treat security alert delivery as a control
A login alert in the junk folder is a failed control. Monitor its placement the way you would monitor any other security mechanism.
Check at onboarding, where the address becomes the account
It carries statements, alerts and recovery flows from that point on, and correcting it later means an identity check rather than a form edit.
Publish BIMI once DMARC is enforced
A checked logo in the inbox is a recognition signal for customers trying to tell your mail from an faking of it.
Questions people ask
Why does DMARC matter more in fintech?
Because financial brands are the most faked in email. Without enforcing, anyone can send from your exact domain and receiving servers have no instruction to stop them.
Is p=none enough?
No. It collects reports and changes nothing about what receivers do with forged mail. Only quarantine or reject stops exact-domain spoofing.
Does checking help with fraud?
Not directly. It stops you sending statements to addresses that do not exist. Sender checks are what stop somebody else sending as you, and those are different problems.
