example-of-sending-emails-using-templates

Example of sending emails using templates

This will use Postmark's withTemplate endpoint.

import Swoosh.Email

new()
|> from({"T Stark", "tony.stark@example.com"})
|> to({"Steve Rogers", "steve.rogers@example.com"})
|> put_provider_option(:template_id, "123456")
|> put_provider_option(:template_model, %{name: "Steve", email: "steve@avengers.com"})

You can also use template_alias instead of template_id, if you use Postmark's TemplateAlias feature.

When sending batch emails using :deliver_many do not mix emails using templates with non-template emails. The use of templates impacts the API endpoint used and so the batch email collection should be of the same format.

Example of sending emails with a tag

This will add a tag to the sent Postmark's email.

import Swoosh.Email

new()
|> from({"T Stark", "tony.stark@example.com"})
|> to({"Steve Rogers", "steve.rogers@example.com"})
|> subject("Hello, Avengers!")
|> put_provider_option(:tag, "some tag")
