The challenge

What regulated products need from email

Problem

You must prove what was sent and when

How we help

Message logs and audit trails record every send and every setting change.

Problem

Phishing erodes trust in your brand

How we help

DMARC enforcement and monitoring protect your domain from spoofing.

Problem

Access to sending must be tightly controlled

How we help

Scoped keys, IP allowlists, roles and SSO limit who can send.

How a message travels

From your app to the inbox, with checks at every hop

Your appSends by SMTP or API with your key.
IntakeAuthenticates, validates and rate-checks the request.
Queue and routingPrioritises mail and picks the right IP pool.
Signing and deliverySigns with DKIM and delivers with provider-aware pacing.
Inbox and eventsDelivery, bounce and engagement events flow back to you.

Overview

Fintech email with MigoSMTP in short

Use cases

Where teams use it

Transaction alerts

Deliver real-time debit, credit and transfer notices with delivery events stored against each transaction so you can show when a customer was notified. This supports later dispute review.

One-time passcodes

Send short-lived codes on their own priority stream, monitor delivery time per provider and alert when delays threaten sign-in or payment completion. Resend options reduce abandoned sign-ins.

Statements with attachments

Distribute monthly statements as attachments or secure links on a schedule, throttled sensibly, with bounce handling that triggers address correction. Failed deliveries then trigger a follow-up review.

KYC and security notices

Send document requests and account-change notices from an enforced DMARC domain, so customers can trust genuine messages and spoofed ones are rejected. Clear sender identity reduces confusion.

AI features

AI-assisted fintech email

Anomaly

Sending anomaly flags

Detect unusual volume, new recipients or off-hours bursts on an API key and raise a flag. A person reviews it and decides whether to pause or revoke the key.

Risk flags

Lookalike and spoofing risk

Review DMARC reports and flag sources that resemble legitimate mail but fail alignment. Findings are shown to your security team, who decide on policy changes.

Privacy

Privacy-first redaction

Redact personal and account details before any content is analysed by AI, and let administrators switch AI analysis off entirely. [Confirm data handling and retention with your compliance team.]

Copilot

Delivery copilot

Ask in plain language why an OTP was delayed and get a log-based summary by provider. The copilot is read-only and changes no setting. Answers cite log entries.

AI features are assistive, your team stays in control of every action, and regulated data handling must be confirmed with the customer's compliance team before use. [Confirm which AI features are available at launch.]

Best practices

Best practices for fintech email

Move DMARC to enforcement

Start at monitoring, fix alignment for every legitimate source, then step up to quarantine and reject to stop spoofing of your brand.

Isolate OTP and alert streams

Use a separate domain or IP pool for authentication mail so it is never queued behind statements or promotions.

Scope keys to the minimum

Issue keys per service with limited permissions and optional IP allowlists, and rotate them on a schedule your security team sets.

Never put sensitive data in the body

Send a notice and a link to an authenticated area rather than balances or account numbers, in case email is intercepted.

FAQs

Fintech email: frequently asked questions

What is the best way to send OTP emails reliably?

Send OTPs on a dedicated stream from an authenticated domain, keep the message short, and track delivery time by provider. Alert on delays, offer a resend option in the app, and consider another channel as fallback. Keep codes short-lived. [Confirm delivery-time targets.]

How do I stop phishers spoofing my financial brand's email?

Publish SPF and DKIM, then enforce DMARC with a quarantine or reject policy once reports show all legitimate sources aligned. Review DMARC reports regularly, and use a separate subdomain for third-party senders so you can control each source. Re-check after any vendor change.

Do I need an audit trail for transactional email?

Many financial teams do, to answer disputes and internal reviews. A message log with timestamps, recipient, status and a record of setting changes helps. What you must retain depends on your regulator. Export logs where your policy requires. [Confirm retention requirements with your compliance team.]

Is MigoSMTP compliant with financial regulations?

[Confirm compliance position.] Compliance depends on your obligations and how you configure and use the service. Check certifications, data location and contract terms with your compliance team, and review the Trust page for what is currently documented. Do not rely on assumptions.

How should I control who can send email from our systems?

Use scoped API keys per service, role-based dashboard access, SSO where available and IP allowlists. Review the audit log for key creation and changes, and revoke unused keys promptly. Remove access promptly when staff change roles. [Confirm SSO and allowlist availability.]

Should statements be sent as attachments?

Attachments are convenient but sensitive. Many teams send a notice with a link to an authenticated download instead. If you attach files, keep them within size limits, consider encryption, and confirm the approach with your security team. [Confirm attachment size limit: [limit].]

Can AI be used safely with financial email?

It can, if controlled. Use redaction so personal data is not exposed, keep AI analysis optional, and require human review of every flag or suggestion. Confirm data handling with your compliance team first. [Confirm which AI features are available at launch.]

How can AI detect suspicious email sending?

Models compare current sending against normal patterns for each key, such as volume, recipients and timing, and flag outliers for review. They do not block anything by themselves; your security team decides whether to act. [Confirm which AI features are available at launch.]
