Tacitry is an AI email agent — it drafts in your voice and sends per-recipient autonomously once trust is earned. Spark is a polished email client. Different layers of the stack; not substitutes. Spark is one of the better-designed email clients of the last decade — Smart Inbox, threads you can comment on with teammates, send-later, calendar integration. Tacitry is at a different layer: not a client, not even visible most of the time. It drafts in the background, surfaces what needs your decision, and sends what it has earned the right to.
Why do people use Spark?
- Beautiful UI across iOS, macOS, Android, Windows.
- Built-in team email — comment on threads internally before replying.
- Solid free tier; team plans start at $7/user/mo.
How is Tacitry different from Spark?
- Spark is a UI; Tacitry is an agent. The two are not substitutes.
- Voice learning + per-recipient autonomy is not a feature you can add to a client; it requires the drafting loop Tacitry is built around.
- CRM context in drafts is not on the Spark roadmap.
Switching from Spark takes about a day. We do the setup; you keep your inbox.

Frequently asked
- Does Tacitry have a desktop or mobile app?
- Not yet. You stay in Gmail (or your Gmail client of choice, including Spark) and use Tacitry's web review queue for drafts you need to decide on.
- Can I use Spark with Tacitry?
- Yes. Both connect to the same Gmail account; Tacitry sends RFC-compliant mail that Spark renders normally.
- What about team collaboration?
- Tacitry is single-user today. Team workspaces are on the roadmap once the autonomy curve is solid.
