In transactional email

<%body%>
Hello :name!, what's up
your number is :number.
This is the transactional footer

how to pass the variables :number, :name??

thanks,

Those are passed in the sendgrid smtp headers defined in X_mailer.rb as an array of strings. The format you define the placeholders in your email content should match the substitution tag's key. So ":name" wouldn't work if your headers had "%name%"

headers "X-SMTPAPI" => {
    "sub": {
      ":name" => [user.name],
      ":number" => [amount]
    }.to_json

# the 'to' email can be overridden per action
mail(
  from: 'test@test.com',
  to: 'recipient@test.com',
  subject: "Hello World"
)
