Templates trapped in code
A copy change requires a PR, review, and deploy. Marketers can’t fix a typo without filing an engineering ticket.
BYOP Email Platform
The control plane between your code and your customers’ inboxes.
Developers trigger transactional email via API. Marketing sends broadcasts via CSV. Both use the same versioned, approved templates — routed through providers you already pay for.
POST /send
telex.send(
template: "welcome-v3"
)The Problem
Modern email is split down the middle — and both sides are broken.
ESPs charge a contact tax
60K registered users × Mailchimp pricing = $300–500/mo to send one changelog a month. That’s a tax on growth, not a tool.
Production ships without guardrails
No diffs, no audit trail, no rollback. A broken token hits 50K inboxes before anyone notices.
Single-provider lock-in
One IP blacklist, one account freeze — and your password resets stop working. No failover, no leverage.
The Moat
Template governance, not just delivery.
Once a team’s templates run through approval gates and version history, switching costs are real and compounding.
- Immutable versions — every save is a numbered snapshot
- Visual diffs — side-by-side rendered comparisons
- One-click rollback to any prior version
- Approval gates before anything goes live
Variable fallback
{{ user.first_name | default: "there" }}Unmapped variables are caught at lint time, not in production.
