Merging donation amount in thank you email

As a non-profit we receive donations. I have a thank you page set up in a campaign. My question is how to add a merge field into a thank you email with the donation amount so the donor can keep the email for his tax records. Thank you.

Most e-commerce products (including Infusionsoft) allow you to send a separate email receipt. Have you explored that?

Thanks Brett. Yes, I have worked this out… Appreciate your help… Be blessed.
