INK review
INK pairs encrypted email with aliases, imports and sync, starting at $6 per month.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
INK is a paid encrypted email service for people seeking privacy-focused personal or professional email. It combines end-to-end encryption using post-quantum cryptography with temporary addresses and aliases, email imports, and connections through IMAP, SMTP, and Exchange. Web, desktop, and mobile apps, plus a built-in calendar and contacts, broaden its scope beyond encrypted messaging. The homepage says the service is invite-only, so access is a practical consideration for individuals and organizations evaluating it.
The published monthly plans start with Drop at $6, which includes 10 GB of storage, 10 aliases, one custom domain, and community support. Bottle costs $8 per month and raises those limits to 20 GB, 20 aliases, and five custom domains, while adding priority support. Bucket is $10 per user per month, with 25 GB per user, 25 aliases, 10 custom domains, priority support, and SSO and SCIM. The tiers make the differences in storage, aliases, domains, and support explicit; teams that need user-based billing and identity administration have a distinct option. Pick a plan based on those limits and whether the team features apply to your use.
INK also includes scheduling and snooze, webhooks and API access, and a public profile with a customizable contact form. Its team administration features include an admin console, management, and audit logs, while imports are listed for Gmail, Yahoo, Outlook, and other providers. This breadth may suit someone consolidating email, calendar, aliases, and team controls in one service. On the other hand, invite-only availability may not work for someone who needs immediate access, and the paid starting price may not fit a buyer seeking a no-cost option. INK is worth considering for users who specifically want post-quantum encrypted email and these additional tools; those who prioritize open availability or a lower entry cost should look elsewhere.
