From your real mailbox
Email you send through the API shows up in the mailbox's Sent folder, and replies land in its inbox.
Enterprise
Email API
Let your website, CRM or ERP send email from your business address, like orders@yourcompany.com, and read incoming mail. Integrate our email API or SMTP in minutes.
Read incoming email too
List the latest messages, read a single message and move the ones you have processed to the trash.
Ready to deliver
SPF, DKIM and DMARC are already set up on your domain, so your email goes out authenticated.
A key per mailbox
Each key works only for its own mailbox. The mailbox password is never used by the API.
Built for developers

Frequently asked questions
What is an email API?
It is an interface that lets your software send and read email. With the Perap Mail API, your website or business software sends email on behalf of your business mailbox over HTTPS and reads incoming messages.
How is it different from SMTP?
You can send with SMTP too; every mailbox supports it. The API is a simpler way that works with JSON, lets you read incoming email and returns clear error codes.
Can I send bulk email?
The API is for individual messages such as orders, appointments and form notifications. For newsletters and campaigns, use our Bulk Email service, where unsubscribes and list cleaning are automatic.
What are the limits?
Up to 10 recipients per email, a per-minute request limit per key and the mailbox's daily sending limit. These limits protect your domain's reputation.
Is it secure?
Connections are HTTPS only. Each key works only for its own mailbox, the mailbox password is never used, and you can renew a key at any time. Built on GDPR compliant infrastructure.
Which languages can I use?
Any language that can make an HTTP request: PHP, Node.js, Python, Ruby, Java, Go, C# and more. No special library is needed.
