You cannot drive successful campaigns for clients if your deliverability is weak.
Inbox placement is getting harder. Spam filters don’t just scan emails—they scrutinize senders, domains, and content like never before. Most deliverability solutions are struggling to keep up.
Warming pools are filled with custom providers. But interactions from irrelevant providers fail to move the needle for your sender reputation.
You need interactions from trusted platforms like Google Workspace and Office 365 to get results.

You can have a great sender reputation and still land in spam because of your content or sending setup. That’s why you need built-in spam testing.
So you can check your actual deliverability and ensure nothing triggers spam filters.
