Zoho ZeptoMail: sovereignty score and 8 European alternatives

ZeptoMail is a transactional email service for applications that send messages automatically. Mail is sent through an email API or an SMTP relay. According to the product page, its infrastructure is isolated from marketing traffic. ZeptoMail is the email channel of Zoho CPaaS, Zoho's communications platform, and is offered as an online service.

Zoho Corporation is privately held and says it has never taken outside investment. It is headquartered in Chennai, India, and according to its company timeline it established its own data centres in the Netherlands and Ireland in 2016. The ZeptoMail page lists data centre regions only for other channels, such as voice in the US, India, the EU and Australia, and does not say which region carries email traffic. A European organisation should therefore confirm the data centre for its account with the provider before sending personal data through the service.

Why digital sovereignty matters with Zoho ZeptoMail

Zoho ZeptoMail is headquartered in IN, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor.

Zoho ZeptoMail hosts data outside the EU (OTHER). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Zoho ZeptoMail is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Zoho ZeptoMail together with your other vendors and gives a total score, a heatmap and the main risk drivers.
