Custom Tracking Domains

In order to collect and report on your campaign's clicks, opens, and unsubscribes, BigMailer uses tracking links in your email's HTML. An example click tracking url appearing in an email looks like:

https://bml.co/t/c/c59e81c5-1031-43a6-8fc2-b7c91bf170e9/01b3d124-91da-4ee0-9ff6-b4b9bf9b69a9

By default, these links use a hostname BigMailer manages on your behalf, such as bigmailer.link or bml.co. For most users, these host names will be fine. However, certain email clients such as Gmail sometimes flag these hosts as suspicious. For example, Gmail flags links as suspicious if the host in your email links (urls) suddenly change. This can happen when the email platform you use changes, such as when switching from Mailchimp to BigMailer.

In order to improve deliverability and reduce the likelihood your contacts experience warning messages when receiving and clicking on links in your emails, we recommend configuring your brands to use a custom tracking domain for each sender domain. For example, if you send email from [email protected], we recommend configuring clk.example.com as your custom tracking domain. A custom tracking domain makes it look like the tracking links are hosted on your site and thus makes your emails look more authentic and trustworthy.
