I am trying to deploy an API with Heroku, using Elixir and Phoenix. In some use cases, I need to send an HTML email (that is all figured out and sending properly), however, images used on the email body are not being sent. This images are under: priv/static/images.

On the email body I am using:

src="<%= Routes.static_url(@conn, "/images/logo-default.png") %>"

This works on development mode. Emails sent to localhost:4000/sent-emails render with the images. But in production, the emails sent, arrive to mailbox without them.

If I lookup localhost:4001/images/logo-default.png (running locally) or in Heroku https://agile-fortress-72183.herokuapp.com/images/logo-default.png I can see the images. Either way none of them serves the images on email.

I'm not using a Phoenix buildpack because the only files I want to serve are this images to be part of email HTML body.

[UPDATE]

After a while, and some research I noticed that the email clients are blocking the images. So, how do I send an html body email with images, like the ones on newsletters and so. I am using Bamboo adapter and Mailgun to send the emails.

Any solutions to fix this problem?

  • - can you give part of the email HTML code received ? – TheSquad Aug 14 at 9:34
  • - Are you sure the image is not loading up because your email client blocks it ? – TheSquad Aug 14 at 9:35
  • @TheSquad after a while I noticed that it is probably the email client that is blocking the images like you said. I’m going to update my question. – zediogoviana Aug 14 at 10:22

Unfortunately because the email client is the decision point there isn't too much you can do. Your best bet would be to ask your recipients to whitelist your email address.

  • I came to conclusion that in some email client the images are blocked by default, but others load by default. So, you're right, there is nothing I can do, it depends on the email client used. – zediogoviana Aug 15 at 15:27
