The transactional email API developers actually enjoy
A clean REST API, standard SMTP, and event webhooks — send your first email in minutes, then rely on authentication and delivery logs that just work.
Sound familiar?
The email headaches Bitelio was built to remove
- 01
Provider SDKs are bloated, poorly typed, or abandoned — you end up reading the raw HTTP docs anyway.
- 02
You can send email, but you can't see what happened to it: no per-message logs, no delivery or bounce events.
- 03
SMTP-only services force you to run a queue and retry logic yourself just to send reliably.
- 04
Deliverability is an afterthought bolted on later, so your first production emails bounce or land in spam.
Why Developers choose Bitelio
One platform, every email you send
REST API or SMTP, your choice
Call a simple JSON endpoint or point any SMTP client at Bitelio. Same deliverability, same logs, whichever you prefer to integrate.
Webhooks for every event
Subscribe to delivered, opened, clicked, bounced, and complained events and react in your own backend in real time.
Send from anywhere
A language-agnostic HTTP API works with Node, Python, Go, Ruby, PHP, or a plain curl command — no SDK required, though examples are provided.
Deliverability from day one
Guided SPF, DKIM, and DMARC setup plus free checker tools mean your domain is authenticated before you send a single message.
Inspect every message
Full logs for each send with status, headers, and events, so debugging a missing email takes seconds instead of a support ticket.
No lock-in
A plain HTTP interface plus full data export via the API mean you never get locked into a provider you cannot leave.

Frequently asked questions
Does Bitelio have a REST API for sending email?
Yes. Bitelio exposes a simple JSON REST API for sending transactional email. Authenticate with an API key and POST your recipient, subject, and body to send in a single request. See the email API guide for examples.
Can I use Bitelio over SMTP?
Yes. Point any SMTP client or library at the Bitelio SMTP relay using your credentials. You get the same deliverability and message logs as the REST API without changing your existing mail code.
Which languages and SDKs are supported?
Because the API is plain HTTP, it works from any language — Node, Python, Go, Ruby, PHP, and more. You can call it directly or use the provided examples; no heavyweight SDK is required.
How do I receive delivery and bounce events?
Configure a webhook endpoint and Bitelio will POST delivered, opened, clicked, bounced, and complained events to your backend as they happen, so your app always knows the state of every message.
How do I set up SPF and DKIM?
Bitelio walks you through adding SPF and DKIM records for your domain, and our free SPF checker and DKIM checker let you confirm they resolve correctly before you go live.
Is there a free tier for development?
Yes. You can sign up and start sending on a generous free tier without a credit card, which is ideal for building and testing before you scale.
