As part of their on-going spam reduction efforts, some large email hosting providers have begun implementing a protocol called Domain-based Message Authentication, Reporting & Conformance (DMARC).
This protocol prevents you from using gmail.com, aol.com, and yahoo.com From addresses for your Drip emails by instructing email delivery software to refuse any such email unless it originates on those company’s servers.
Note that other providers will also be adopting this protective measure going forward.
If you specify an email address from one of these protected domains as a “from email address” in Drip, you will get an error message as follows:
To resolve this problem, please use a regular corporate email address. If you do not have one, you can set up custom domain email hosting on Google Apps or various other Internet service providers. Your domain name provider (for example, godaddy.com, squarespace.com, etc.) should also provide resources on how to set up a custom email domain.
Using regular corporate email addresses is worthwhile regardless of DMARC restrictions—it will build confidence in your brand with your customers and prospects.
