What users say about Unitpost
Zain Sheikh
Transactional email is one of those things nobody notices until it breaks, so having AI agents draft the receipts and password resets is a smart place to start. Do you handle deliverability warmup too?
Mike from Unitpost
Hey Uneed — Mike here, CEO @ Unitpost ✌🏻
Most teams I know still run two email tools:* an API for transactions / receipts* a marketing tool for campaignsContacts drift. Two bills. Agents can draft copy, then someone finishes it by hand.
We built one system instead. One contact list, one sending balance, same actions in the dashboard, API, SDKs, and MCP — so Claude, ChatGPT, Gemini, or your IDE can run those actions too. Describe a welcome email or a campaign and Unitpost builds the templates and connects the steps. You approve before anything goes out.
Setup is short: paste your site for Brand Kit, verify the domain.
optional: migrate from Resend / Postmark / Mailgun / SendGrid / Brevo / Loops in < 5 minutes.
Email is live. Automations, SMS, and WhatsApp are next — same system.
