One-to-one emails triggered by an action, such as order confirmations, OTPs, password resets and invoices.
New: Own SMTP plans now start at ₹2,999 a year with unlimited sending. See plans →
Send order confirmations, OTPs, password resets and invoices from your app or website through a simple REST API, with the same deliverability tools as your campaigns.
Ideal for ecommerce stores, SaaS products, booking systems and internal tools.
An OTP that lands in spam or an order confirmation that never arrives costs you sales and support time. Transactional emails need fast, reliable delivery from an authenticated domain.
GO MAILBOX gives your developers a REST API to send these emails and manage subscribers. You choose the route: our managed servers, or your own SMTP or Amazon SES account, so important system mail is never stuck behind a big marketing send.
Add SPF, DKIM and DMARC records so mailbox providers trust your mail.
Generate a key for your app or website in the dashboard.
Call the REST API to send emails or add and update subscribers.
Track delivered, bounced and failed messages in reports.
Reliable sending with as little setup as possible.
Send emails and manage subscribers with standard HTTP requests.

What are transactional emails?
One-to-one emails triggered by an action, such as order confirmations, OTPs, password resets and invoices.
How do I send transactional emails?
Use the GO MAILBOX REST API from your website or app. The API also lets you add and update subscribers.
Can I keep transactional and marketing mail separate?
Yes. You can route them through different servers or SMTP connections so marketing traffic does not affect important system emails.
