For over 12 years CloudMailin has provided our customers with the ability to receive email via API as a webhook. In recent years we've also added an outbound email API that allows customers to send transactional email via HTTPS (or send messages via SMTP), making inbox delivery clear and simple.

There are multiple ways to send and receive email with Go (Golang). In this article we'll take a look at a couple of them and why we think using HTTP is actually a great method vs SMTP, IMAP and POP3.

In this article we discuss webhooks, what they are and how you can use webhooks for both email to webhook and sending email events.

CloudMailin allows you to store or backup an entire email in either EML format or fully parsed JSON. Full Emails are stored within an AWS S3 bucket, Azure Blob Storage or Google Cloud Storage and delivered to your webhook, creating an encrypted backup with API for your web application.

Learn the difference between the main SMTP client and server ports (Port 25, 465, 587 and 2525), which one you should choose, what Start TLS is, and why you shouldn't use port 25 to send email messages.

CloudMailin allows you to receive email attachments directly to Cloud Storage such as AWS S3. Starting Oct 15 2021 these links will use HTTPS.

In this article, we'll discuss how to get TypeScript working with AWS Lambda and AWS SAM in just a few easy steps.

In this article, we cover what AWS SAM is, how to get started and how it helps deploy serverless applications and Lambda functions to Amazon Web Services. We'll use JavaScript here, but AWS supports a range of languages.

In this article, we'll cover a couple of ways to send email in Node.js and TypeScript. Following this we'll outline a quick and easy way to receive email with CloudMailin.

CloudMailin can parse the attachments from email and send the email attachment to Google Cloud Storage automatically.

Basic authentication is one of the oldest and simplest ways to authenticate HTTP Traffic. Although it has been superseded by a range of different options it's still one of the easiest and most convenient methods, as long as you're using HTTPS.

CloudMailin allows you to receive emails via an HTTP POST, essentially sending email to a webhook.

Security has always been a priority for us at CloudMailin. As an email service provider it's often necessary for us to balance customer requirements and usability and where possible we always give our users a choice. For a while now we've supported both TLS 1.2 and TLS 1.3 on our platform, but we've also allowed connections from servers using TLS versions lower than this if the customer requests it.

When we first started over 10 years ago our original HTTP Webhook format was our only option. The original HTTP Format was a multipart/form-data format that was opinionated, it made a lot of decisions about how you might use it.

In an earlier article, we covered what DKIM and SPF can do for a domain. DMARC is the extension that brings it all together. DMARC stands for "Domain-based Message Authentication, Reporting & Conformance".

Sender Policy Framework (SPF) and DomainKeys Identifier Mail (DKIM) are both methods of identifying email senders.

Email sender reputation is crucial when sending an email. Since the early 1990s people have been sending Unsolicited Bulk Email or SPAM and it's critical you understand how to check and manage your reputation.

For a while now CloudMailin has allowed you to send your attachments to S3. We call this feature attachment stores, but what exactly does this mean?
