Email Receipt Testing Made Simple with Mailinator

Ensure flawless email workflows, every time.

When customers complete a transaction, their email receipts are crucial touchpoints. Whether it’s an order confirmation, a payment receipt, or a subscription notice, flawless delivery and rendering are essential for customer trust and satisfaction.

Mailinator’s Email Receipt Testing empowers QA teams, developers, and product managers to automate and validate email receipts at scale — ensuring every customer receives accurate, branded, and timely emails.

Why Is Email Receipt Testing Important?

Transactional emails, especially receipts, have the highest open rates of any email type — often exceeding 70%. They also carry legal, financial, and reputational importance. Errors in these emails can result in customer frustration, charge disputes, or even compliance issues.

Testing your email receipts helps you:

  • Validate content accuracy (amounts, items, taxes, discounts)

  • Confirm email deliverability and sender reputation

  • Ensure mobile and desktop rendering consistency

  • Verify personalization fields (name, order number, address)

  • Check links and attachments for functionality

  • Stay compliant with receipt-related regulations (like CAN-SPAM and GDPR)
