AI & email

Is it safe to let AI read your email? A checklist.

The right question isn't whether, it's which. Seven checks that separate trustworthy AI email tools from the rest.

TL;DR

Before connecting any AI tool to your inbox, verify seven things: no training on your mail, recognized security audits (SOC 2 or ISO 27001), OAuth access you can revoke instantly, clean data deletion on disconnect, draft-and-approve sending, a readable privacy policy, and GDPR compliance if you're in Europe. Tools that pass all seven are handling email more carefully than most humans do.

"Would you let an AI read your email?" is the wrong question, in the same way "would you let a company hold your money?" is the wrong question. You already trust your mail to Google's or Microsoft's machines, which scan it for spam, malware, and search indexing. The real question is which additional party you're admitting, under what terms. Terms are checkable. Here are the seven checks.

The seven checks

CheckWhat good looks like
1. Training useYour mail is never used to train models. Stated plainly in the privacy policy, not implied.
2. Security auditSOC 2 Type II or ISO 27001. An external auditor verified the controls; the vendor didn't just describe them.
3. Access mechanismOfficial OAuth via Google or Microsoft. No password sharing, ever, and access is revocable from your account settings in one click.
4. DeletionDisconnecting deletes your processed data, on a stated timeline. "Deleted" means deleted, in writing.
5. Sending controlDraft-and-approve. The AI writes; you review and send. Nothing leaves your account without your click.
6. Policy readabilityYou can find and understand the data handling section in five minutes. Impenetrability is a signal.
7. JurisdictionGDPR compliance if you're in Europe, with a data processing agreement available for business use.

How to verify without being a lawyer

Three sources, fifteen minutes: the vendor's security page (certifications are always displayed when they exist; absence is an answer), the privacy policy's data-use section (search it for "train"), and your own Google or Microsoft security settings after connecting, where the OAuth grant appears and where one click revokes it. If any of the seven can't be verified in those fifteen minutes, that's your answer.

The honest risk framing

A tool passing all seven checks handles your mail with more explicit controls than most human assistants ever operated under, and the value trade is the same one executives have always made: access in exchange for hours. Pidgy is built to pass this list (OAuth-only access, no training on your mail, draft-and-approve on every send, clean deletion on disconnect), and the same checks apply to any tool in the category. What machines can do with the access, once granted safely, is covered in what to delegate and what to keep.

Frequently asked questions

Can AI email tools read all my messages?

They read what you grant via OAuth scopes, which for triage and drafting means message content. The meaningful questions are what happens next: whether content is stored beyond processing, whether it trains models (it shouldn't), and whether deletion is real when you disconnect.

What security certifications should an AI email tool have?

SOC 2 Type II is the working standard for SaaS handling business data; ISO 27001 is its international sibling. Either means an external auditor has verified the security controls rather than the vendor merely describing them.

Can I revoke an AI tool's access to my email?

Yes, and it should take seconds. OAuth connections appear in your Google or Microsoft account's security settings, where one click cuts access. A trustworthy vendor also deletes your processed data on disconnect and says so in writing.
