I’m having trouble with my Rails app’s email functionality. I’ve set up ActionMailer with Mailgun, but all the emails are going straight to the spam folder. Here’s what I’ve done:
In my mailer class:
class NotificationMailer < ActionMailer::Base
include AsyncMailer
default 'Message-ID' => "<#{SecureRandom.hex}@example.com>"
default from: '[email protected]'
end
My email headers look like this:
From: [email protected]
To: [email protected]
Message-Id: <[email protected]>
And in my production.rb:
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
authentication: :plain,
address: 'smtp.mailgun.org',
port: 587,
domain: 'example.com',
user_name: '[email protected]',
password: 'mypassword'
}
I’ve followed best practices, but emails still end up in spam. Any ideas what could be causing this? I’m stumped!
I’ve faced similar issues with email deliverability in Rails apps. One thing that helped me was setting up proper SPF and DKIM records for my domain. These authentication methods can significantly improve your email reputation.
Also, consider the content of your emails. Spam filters are pretty sophisticated these days. I found that keeping the HTML simple, avoiding too many links, and using a balanced text-to-image ratio helped my emails land in the inbox more consistently.
Another trick that worked for me was gradually ramping up my email volume. I started with a small number of emails per day and slowly increased it over time. This helped build a positive sending reputation with ISPs.
Lastly, don’t forget to monitor your delivery rates and engagement metrics through Mailgun’s dashboard. It can provide valuable insights into why your emails might be getting flagged as spam.
hey man, i had similar issues. try warming up ur IP gradually. start with low volume n increase slowly. also, check ur content. avoid spammy words n keep HTML simple. oh, n make sure ur domain has good rep. google postmaster tools can help with that. good luck!
Have you considered using a dedicated IP address for your email sending? Shared IPs can sometimes be problematic if other users have poor sending practices. Mailgun offers dedicated IPs which can help improve deliverability.
Another aspect to look into is your domain reputation. Tools like Google Postmaster Tools can provide insights into how your domain is perceived by email providers. It might reveal issues you weren’t aware of.
Also, ensure your emails have a clear unsubscribe option. This is not only a legal requirement in many places but also helps prevent users from marking your emails as spam.
Lastly, consider implementing DMARC in addition to SPF and DKIM. It adds another layer of authentication and can significantly boost your email deliverability.
