The article recommends migrating from the cloud email feature because the previous API could lead to blacklisting and delivery failures, while clarifying that the standard send email APIs remain unaffected. ### Source excerpt When we announced the migration to the new cloud servers one of the casualties was the cloud email API. This was a well intentioned API for sending an email from an app. Unfortunately we didn't understand the complexities of modern mail systems well enough when we came up with this API. It turns out that this is pretty problematic. Mail servers get blacklisted and emails fail to deliver. ## GKE in production DevFeed: [GKE in production]() Original publisher: [Read original article]() Author: Carlos Alexandro Becker Published: 2017-07-02T00:00:00Z Content type: tutorial Language: en Sources: [Carlos Becker]() Topics: [Gke](), [Google Cloud Platform (GCP)](), [Kubernetes](), [Amazon Web Services](), [Digital Ocean]() Tags: [aws](), [cloud-sql](), [digitalocean](), [gke](), [google-cloud](), [health-checks](), [heroku](), [ingress](), [kubernetes](), [postfix](), [sendgrid](), [spinnaker]() ### AI overview A developer describes deploying small applications on GKE and lessons learned from moving between AWS and Google Cloud.

Emails are serialized and stored, metadata is placed in RabbitMQ queues, and workers reconstruct and deliver messages through SendGrid, with priority queues used to reduce waiting time. ### Source excerpt At hackerearth we send emails to keep our users updated on upcoming challenges and their activities, for example, when a user successfully solves a problem, receives test-invitation, updates on user comments. Basically whenever it is appropriate. Architecture It takes lot of computational power to send emails in such large quantities synchronously. So we have implemented an asynchronous architecture to send emails. Here is brief overview of the architecture: Step 1: Construct an email and save the serialized email object in database. Step 2: Queue the metadata for later consumption. Step 3: Consume the metadata, recreate the email object and deliver. The diagram below shows high level architecture of emailing system. The solid line represents the data flow between different components. The dotted line represents the communications. Hackerearth email infrastructure consists of MySQL database, MongoDB database, RabbitMQ queues. Journey Of Email Step 1 - Construct email: There are two different type of emails. Text - Plain text emails Html - Emails with rich interface using html elements. These emails are made using django templates API used by hackerearth developers for sending email - send_email(ctx, template, subject, from_email, html=False, async=True, **kwargs) The above API creates Sendgrid Mail object, serializes and saves it in the db with some additional data. A piece of code similar to the bit shown below is used to create sendgrid Mail object import sendgrid sg = sendgrid.SendGridClient('YOUR_SENDGRID_API_KEY') message = sendgrid.Mail() message.add_to('John Doe ') message.set_subject('Example') message.set_html('Body') message.set_text('Body') message.set_from('Doe John ') status, msg = sg.send(message) Model below is used for storing the serialized mail object and additional data. class Message(): # The actual data - a pickled sendgrid.Mail object message_data = models.TextField() when_added = models.DateTimeField(default=date
