Authorized Recipients

Article Preview


    If you're on the Free plan without credit card information present or using your sandbox domain for testing, you're restricted to sending just to Authorized Recipients.

    Restricting a domain or an account to a fixed set of verified email addresses makes them less useful for spammers. At the same time, you could still test the service right away, with no extra steps like adding a credit card, which upgrades your account, to allow you to add custom domains. From custom domains, you can send to whomever you like!

    But say you're not ready for that just yet; you're wanting to ensure our service is a good fit, and are looking to configure Authorized Recipients to prove this. We'll show you how to do this below:

    1. First, log in to the Mailgun Control Panel (if you have not already done so).
    2. Then, within the left-hand navigation pane, click the Send product and then click the Sending option to expand its list of suboptions.
    3. Next, click the Domains suboption.
    4. Ensure that the domain in question (the sandbox domain, which is a long domain name starting with "sand") is displayed within the Domain drop-down list towards the upper-right portion of the page.

    5. On the right-hand side of the page, you may enter a new or view/remove an existing Authorized Recipient.

    Up to 5 Authorized Recipients can be added.

    After a recipient accepts the invitation by clicking on the activation link, they become "Verified," and you can send messages to them. Until then, the recipients are considered "Unverified."
