What is Postfix and what are its top alternatives?
Postfix is a popular open-source mail transfer agent (MTA) that is known for its speed, security, and reliability. It is widely used for routing and delivering email on Unix-like operating systems. However, Postfix can be complex to configure for beginners and lacks some advanced features compared to other MTAs.
- Exim: Exim is another widely used MTA known for its flexibility and extensive configuration options. It supports various authentication methods and spam filtering capabilities, making it a popular choice for both small and large email servers. However, Exim can be challenging to configure for beginners.
- Sendmail: Sendmail is one of the oldest and most well-established MTAs, known for its robustness and high performance. It provides extensive customization options and supports complex routing configurations. However, Sendmail can be challenging to set up and lacks some modern features found in newer MTAs.
- Qmail: Qmail is a secure and efficient MTA known for its focus on security and simplicity. It follows the "one-program-one-task" approach, making it easy to audit and maintain. However, Qmail has a steep learning curve and lacks some advanced features compared to other MTAs.
- SMTP: SMTP is a lightweight and simple MTA that is easy to configure and use. It is designed for small to medium-sized servers and provides basic email routing and delivery capabilities. However, SMTP lacks some advanced features and scalability options found in other MTAs.
- Mailgun: Mailgun is a cloud-based email infrastructure service that offers powerful email delivery capabilities and tracking features. It provides scalability, reliability, and advanced analytics for email sending. However, Mailgun is a paid service and may not be suitable for all users.
- Haraka: Haraka is a high-performance MTA written in Node.js, known for its speed and extensibility. It supports plugins for customization and has built-in spam filtering capabilities. However, Haraka may not be as widely supported or tested as other MTAs.
- OpenSMTPD: OpenSMTPD is a free and open-source MTA that aims to be simple, secure, and easy to configure. It supports modern email standards and provides built-in security features. However, OpenSMTPD may lack some advanced features and scalability options compared to other MTAs.
- Mailjet: Mailjet is a cloud-based email service provider that offers email delivery, marketing automation, and transactional email capabilities. It is known for its deliverability and scalability for high-volume email sending. However, Mailjet is a paid service and may not be suitable for all users.
- MTA-STS: MTA-STS is a security protocol that allows email senders to specify policies for secure email transmission. It helps prevent man-in-the-middle attacks and other security vulnerabilities in email delivery. However, MTA-STS requires support from both the sending and receiving mail servers to work effectively.
- Mailsac: Mailsac is a disposable email service provider that allows users to create temporary email addresses for testing and development purposes. It provides inbox storage, email forwarding, and API integration for managing temporary email accounts. However, Mailsac is not suitable for production email delivery and may have limitations in terms of scalability and reliability.

Hi, We are looking to implement 2FA - so that users would be sent a Verification code over their Email and SMS to their phone.
We faced some limitations with Amazon SNS where we could either send the verification code to email OR to the phone number, while we want to send it to both.
We also are looking to make the 2FA more flexible by adding any other options later on.
What are the best alternatives to SNS for this use case and purpose? Looked at Twilio but want to explore other options before making a decision.
Would be great to know what the experience with Twilio has been, especially the limitations/issues with Twilio...
Appreciate any input from users of Twilio and others who have had similar use cases.
Searching for options for SMS that integrates with SiteLink and will allow personalization of text and tracking of both incoming/outgoing messages with reporting (Time, date, call#, etc) Have been looking at Twilio, and seems most leaning toward this. Are there any other options known that integrate into SiteLink? Also looked at Clickatell.

At StackShare we were discussing how to increase the retention of our newly signed up users. We hypothesized that if we made certain changes to the emails in our on-boarding process we could increase our retention and activation of users.
We decided to use sendwithus because it offered us the ability to A/B test our transactional emails. We also utilized the sendwithus analytics dashboard to gain real time insight into the performance of our email campaigns. Furthermore sendwithus has a Rails gem that allowed us to easily integrate the product into our application. We were also able to integrate sendwithus with our SendGrid account. #ABTestingAnalytics #TransactionalEmail
Nexmo vs Twilio ?
Back in the early days at SmartZip Analytics, that evaluation had - for whatever reason - been made by Product Management. Some developers might have been consulted, but we hadn't made the final call and some key engineering aspects of it were omitted.
When revamping the platform, I made sure to flip the decision process how it should be. Business provided an input but Engineering lead the way and has the final say on all implementation matters. My engineers and I decided on re-evaluating the criteria and vendor selection. Not only did we need SMS support, but were we not thinking about #VoiceAndSms support as the use cases evolved.
Also, on an engineering standpoint, SDK mattered. Nexmo didn't have any. Twilio did. No-one would ever want to re-build from scratch integration layers vendors should naturally come up with and provide their customers with.
Twilio won on all fronts. Including costs and implementation timelines. No-one even noticed the vendor switch.
Many years later, Twilio demonstrated its position as a leader by holding conferences in the Bay Area, announcing features like Twilio Functions. Even acquired Authy which we also used for 2FA. Twilio's growth has been amazing. Its recent acquisition of SendGrid continues to show it.

We decided to use AWS Lambda for several serverless tasks such as
- Managing AWS backups
- Processing emails received on Amazon SES and stored to Amazon S3 and notified via Amazon SNS, so as to push a message on our Redis so our Sidekiq Rails workers can process inbound emails
- Pushing some relevant Amazon CloudWatch metrics and alarms to Slack
I would like to know how I can implement a transactional email, or if it is possible to do so, like Mailchimp, using Amazon SES. I want to have the flexibility of creating emails like MailChimp, with a bulk email sending capability. Is it as simple with AWS SES as it is with MailChimp? If so, then how can I implement that for my own product? Thanks!

We've moved our transactional email away from Mandrill to Mailgun. We had continued using Mandrill after Mailchimp deprecated the service awhile back, because the amount of credits we were offered essentially made it free.
However, following a couple weeks of frequent downtime and poor service transparency from Mandrill, we decided it was time to make the switch. It appears they no longer had any engineers with the ability to identify the core problems.
Mailgun has been more reliable, yet not as reliable as we expected. We still see issues a few times per week with the API failing when we attempt to make a call. The Reporting UI is way better.

Hi, I've noticed my Mandrill emails are being received fine but my Mailchimp emails, about 75% are going into junk mail. I was wondering is it possible I have missed some sort of integration or can I send my Mailchimp marketing emails via mandrill?
Need help to somehow reduce the number of my emails going into junk mail, can someone help?
