A fix was released to address case sensitivity in the Email Messages API.

The API now treats GET addresses/[email protected]/messages the same as GET addresses/[email protected]/messages.

My garden has been planted and the days are getting warmer. Next task, cleaning up. Mailsac won’t help you organize you garage or avoid the accumulation of clutter. But it can help you get rid of old emails.

The Delete All Messages in a Domain Endpoint released on March 23, 2021 can help you keep your private domain storage under the storage limit. It’s useful for deleting all messages before running integration tests.

This post will detail the different methods of bulk message deletion.

Cleanup a Custom Domain

All messages in a custom domain can irrevocably be deleted.

From the Dashboard select Custom Domains → Select Domain to Mange → Advanced tab → Irreversibly Delete Email

The REST API has a commensurate endpoint for deleting all messages in a domain. It can be invoked by calling an HTTP POST https://mailsac.com/api/domains/{domain}/delete-all-domain-mail , where {domain} is the custom domain.

Cleanup a Private Inbox

All messages in a Private Inbox can be deleted from the website or the REST API. Both methods will not delete starred messages.

From the From the Dashboard select Manage Email Addresses → Select Email Address → Purge Inbox

Messages in a Private Inbox can be deleted using the endpoint for deleting messages in a private inbox. The endpoint can be used with the HTTP DELETE method on https://mailsac.com/api/addresses/{email}/messages where {email} is the private email address.

Deleting Individual Messages

Individual messages can be deleted from both private and non-private inboxes.

From the From the Dashboard enter an inbox in the inbox viewer form and select Check The Mail!. From the Inbox, Click the message → Select Delete → Permanently Delete

Individual messages can be deleted using the delete message REST API. The endpoint can be called using an HTTP DELETE with the URL https://mailsac.com/api/addresses/{email}/messages/{messageId} . The {email} parameter is the email address and the {messageId} is identifier for the message to be deleted. The messageId can be found by using the list messages in an inbox REST API endpoint.

Mailsac API Documentation has been converted over to use OpenAPI.

Code Examples

The new format gives developers and quality assurance testers code samples for common programming languages (curl, Node, Python, PHP, Go, etc).

Explore the API Using Swagger UI

The API can be explored without writing any code using the Swagger UI Explorer. All that is needed to get started is a free Mailsac API Key (requires sign up).

In the Swagger UI Explorer, choose the Authorize button and enter your Mailsac API Key

---

Use the “Try it out” button to interact with any of the REST API endpoints. A curl example, request URL, response body, and headers are provided.

Devs and Quality Assurance Testers Can Easily Validate Mail Headers

The SMTP header endpoint provides quality assurance testers with the option to view an email message’s SMTP headers in parsed formats that easily integrate with automated testing frameworks.

Problem

Developers and QAs are often asked to validate contents of emails. This can include from address, links, and subject. For many organizations this can be a manual process of checking the email and validating if the test criteria has been met.

Solution

Mailsac’s new message header endpoint provides SMTP headers in 3 formats:

1. JSON object format, grouped by lowercased header key. This format is easily consumed by industry standard tools such as Selenium.

{
  "received": [
    "from 107.174.234.77 by frontend1-172-31-29-224 via 172.31.42.57 with HTTP id 8m7iqeiZKJ3MzwTwUQlU for <[email protected]>; Mon Dec 24 2018 15:29:06 GMT+0000 (Coordinated Universal Time)",
    "from 107.174.234.77 by smtp-in2-172-31-42-57 via 172.31.23.10 (proxy) with SMTP id 8m7iqeiZKJ3MzwTwUQlU for <[email protected]>; Mon, 24 Dec 2018 15:29:06 UTC",
  ],
  "from": [
    "[email protected]"
  ],
  "to": [
    "[email protected]"
  ],
  "subject": [
    "invitation to collaborate"
],
  "date": [
    "Mon, 24 Dec 2018 15:29:06 +0000"
  ]
}

2. Ordered JSON array format. This formats pre-parses the headers, but maintains the original order, while still handling duplicate headers such as Received.

?format=ordered-json

[
  {
    "name": "received",
    "value": "from 107.174.234.77 by frontend1-172-31-29-224 via 172.31.42.57 with HTTP id 8m7iqeiZKJ3MzwTwUQlU for <[email protected]>; Mon Dec 24 2018 15:29:06 GMT+0000 (Coordinated Universal Time)"
  },
  {
    "name": "received",
    "value": "from 107.174.234.77 by smtp-in2-172-31-42-57 via 172.31.23.10 (proxy) with SMTP id 8m7iqeiZKJ3MzwTwUQlU for <[email protected]>; Mon, 24 Dec 2018 15:29:06 UTC"
  },
...
  {
    "name": "to",
    "value": "[email protected]"
  },
]

3. Plaintext original format. This format is useful when you are interested in parsing or inspecting the email headers yourself, and do not wish to download the entire message.

?format=plain

Received: from 107.174.234.77 by frontend1-172-31-29-224 via 172.31.42.57 with HTTP id 8m7iqeiZKJ3MzwTwUQlU for <[email protected]>; Mon Dec 24 2018 15:29:06 GMT+0000 (Coordinated Universal Time)
Received: from 107.174.234.77 by smtp-in2-172-31-42-57 via 172.31.23.10 (proxy) with SMTP id 8m7iqeiZKJ3MzwTwUQlU for <[email protected]>; Mon, 24 Dec 2018 15:29:06 UTC

“We are currently using the REST API headers endpoint in support between our own microservices. Our POP3 server fetches headers of message to implement the POP3 TOP command.” — Michael Mayer, Partner Forking Software LLC

Getting Started

The message header endpoint /api/messages/:messageId/headers is available on all Mailsac plans (including our free tier). See our API Specification for more information.

This code example could can be modified to view the headers for the first email message on an inbox [email protected]. Make sure to insert your API Key and change the email address to an email address you which is public or reserved by your account.

const superagent = require('superagent') // npm install superagent

const mailsac_api_key = 'YOUR_API_KEY_HERE' // change this!

superagent
  .get('https://mailsac.com/api/addresses/[email protected]/messages')
  .set('Mailsac-Key', mailsac_api_key)
  .then((messages) => {
      const messageId = messages.body[0]._id
      superagent
          .get('https://mailsac.com/api/addresses/[email protected]/messages/' + messageId + '/headers')
          .set('Mailsac-Key', mailsac_api_key)
           .then((response) => {
               console.log(response.body)
           })
  })
  .catch(err => console.error(err))
