Buyer questions
Questions buyers actually ask
What is a business email?
A business email is an address on your company domain rather than a free address such as @gmail.com.
Do I need a website to have a business email?
No. You need a domain, not a website. DNS records at your registrar point the domain mail to Atomic Mail.
Where is company email stored?
On servers in ISO 27001-certified data centres in Germany. Atomic Mail is operated by AtomicMail Systems OÜ in Tallinn, Estonia, and follows the GDPR.
Can I use Outlook with Atomic Mail?
Not yet. Importing mail and IMAP/SMTP access for clients such as Outlook and Apple Mail are on the roadmap.

The expert review
Atomic Mail scores 58/100, with a clear privacy-focused encrypted email proposition and strong crawlability. Mobile performance and editorial readiness are the most material weaknesses, with interactivity after 14.8 seconds and an emergency-maintenance message dominating the sampled experience.
58/100: based on the sampled public surface, Atomic Mail appears relevant to privacy-conscious individuals and small teams, but mobile and editorial weaknesses hold it back
