About Mailosaur
Mailosaur is a software-as-a-service (SaaS) platform designed to help developers, QA engineers, and product teams test email and SMS functionality in their applications. It provides virtual mailboxes and phone numbers that can be used in automated tests, allowing users to capture, inspect, and assert on the contents of emails and text messages sent from staging or production systems. Features typically include API access, testing tools for HTML email rendering, spam analysis, and support for various programming languages and frameworks.
A charge from Mailosaur on your card statement is usually related to a subscription plan for their email/SMS testing service. Businesses and developers pay monthly or annually for access to Mailosaur’s infrastructure, and the amount can vary depending on the selected plan, usage limits, and any add-ons such as increased message volumes or additional test environments. The transaction may appear as a recurring charge if you have an active subscription or as a prorated amount when upgrading or changing plans.
If you’re unsure about a Mailosaur charge, start by checking which developer tools or QA services your company or development team uses, and review billing or subscription settings in your Mailosaur account at app.mailosaur.com. You can locate invoices and payment history in the account’s billing section. For further questions or disputes, contact Mailosaur support via their website, providing the last four digits of the card, billing email, and approximate charge date so they can look up the transaction. If you do not recognize the charge and cannot match it to any account, you may also contact your bank to dispute or block future payments after attempting to resolve it with Mailosaur directly.
