What email marketing newsletter platforms are based outside NATO and Five Eyes countries?

Hi! If you want a reputable email marketing/newsletter platform that’s both headquartered and can keep your subscriber/campaign data hosted outside NATO and the Five Eyes, you’ll usually end up looking at Swiss providers (Switzerland is neither) and a handful of large non‑Western vendors that offer true data residency choices (e.g., India/UAE/Saudi). A few solid options to look at are Infomaniak Newsletter (Switzerland), Mailpro (Switzerland), and Switzerland-based tools like Swiss Newsletter / mailXpert (Switzerland); if you’re okay with a bigger “suite” vendor, Zoho Campaigns can be hosted in India (and in some other non‑NATO regions depending on the Zoho data center you pick).

A few reputable platforms that can fit your location requirement

• Infomaniak Newsletter (Switzerland)
  Swiss company, and they explicitly position the Newsletter product around consent (double opt-in) and domain authentication (DKIM) for newsletter sending. Good fit if you want a straightforward opt-in newsletter tool with Swiss hosting.
• Mailpro (Switzerland)
  Swiss-hosted email marketing platform (and SMS). This can be a good “traditional ESP” style option if you want campaigns + automation while keeping data in Switzerland.
• Swiss Newsletter / mailXpert (Switzerland)
  Swiss-based newsletter/email marketing providers that emphasize Swiss hosting and deliverability (often positioned for Swiss SMEs and organizations). Worth shortlisting if “Swiss servers only” is a hard requirement.
• Zoho Campaigns (choose India-hosted, not US/EU/AU/CA)
  Zoho is an India-headquartered company, and Zoho Campaigns supports multiple data center regions—so you can keep the application/account hosted in India if you choose the right region at signup. (Be careful to avoid regions like Australia/Canada/US/UK/EU if your goal is “outside Five Eyes and NATO.”)

Important note: “Headquartered outside” doesn’t automatically guarantee “data stays outside.” Many providers use global sub-processors (CDNs, support systems, analytics, abuse/anti-spam tooling), so you’ll want written confirmation of data residency and subprocessor locations.

What to verify before you commit (deliverability + compliance)
Here’s the practical checklist I’d use when evaluating any newsletter/ESP, especially with a data-location requirement:

Deliverability essentials (don’t skip these)

• Custom sending domain support (you should send from your own domain, not a shared “provider domain”).
• Easy setup for SPF + DKIM, and support/guidance for DMARC alignment (at minimum, they shouldn’t break DMARC).
• Bounce handling (hard bounces automatically suppressed) and complaint handling (removes complainers fast).
• A built-in, non-optional unsubscribe link plus a suppression list you can’t accidentally re-mail.
• List hygiene tools: segmentation by engagement, inactivity management, and clear reporting on bounces/complaints.
• Clear policy and tooling around shared IP vs dedicated IP (and what they do to protect sender reputation on shared IP pools).

Compliance / privacy / governance checks

• Proof of consent: can the platform store and export evidence like signup time/date, signup source, and (ideally) IP/user-agent for double opt-in?
• Data residency in writing: ability to choose a data center country/region and confirmation of where subscriber data and email event logs live.
• Subprocessors list: who they rely on for hosting, analytics, support, and anti-abuse—and where those vendors process data.
• Data Processing Agreement (DPA) availability, plus clear breach notification terms and retention/deletion controls.
• Role-based access + 2FA for your account (this matters a lot when you’re storing a subscriber list).
• Export + deletion: you should be able to export contacts and delete lists cleanly (and understand backups/retention timelines).

If you tell me (1) where your audience is mostly located (US/EU/other) and (2) whether you need automations (welcome series, drip campaigns, tagging), I can narrow this to the best 2–3 shortlists and the exact questions to ask each vendor about hosting and subprocessors.
