What it really is

Sendinc — passwordless encrypted email service for regulated-industry professionals.

Our take

Sendinc delivers military-grade encrypted email that recipients open via a browser link — no password, plugin, or account required on their end. The DB mislabels the price_tier as 'free_trial' and the 'who_its_for' field incorrectly describes AI data-pipeline teams; Sendinc is firmly a security tool for healthcare, legal, and financial professionals sharing sensitive documents. A permanent free tier exists (not a trial), with paid Pro and Corporate plans at just $48/user/year.

Why we rate it

At $48/year, Sendinc undercuts most encrypted-email rivals while removing the hardest adoption hurdle: recipients never need an account or plugin. The free plan is genuinely useful for light users, not a crippled trial.

The catch

Encryption is link-based (browser portal), not true end-to-end; a determined attacker with Sendinc server access could theoretically intercept. Feature set is narrow — no built-in DLP policies, archiving rules, or directory sync.

Best for
Healthcare teams sharing PHI who can't ask patients to install software
Legal and finance professionals sending sensitive documents to external parties
Small businesses needing affordable encrypted email with Outlook/Gmail integration
Not good for
Large enterprises needing automated DLP policy enforcement and archiving
Teams wanting true end-to-end encryption without relying on a third-party portal
High-volume bulk secure messaging beyond 200 recipients/day
Friction report
Time to value
Fast: free account in minutes; Outlook add-in or SMTP setup adds ~15 minutes.
Scale breakpoint
Corporate plan is flat $48/user/yr with no volume discount — costs rise linearly at 50+ users.
Walled garden
Moderate: recipients read messages on Sendinc's portal; no export of encrypted threads; integrations limited to Outlook add-in and SMTP relay.
