We recently told you about a policy change by Yahoo that was made to combat spoofing attacks. Unfortunately, as a side effect, if you use a Yahoo email address to send emails from your Constant Contact account, some of those emails might not get delivered.
On Tuesday, April 22, 2014, AOL made a similar change in their authentication policy for people sending from @aol.com email addresses.
This means that if you’re sending email through an email service provider (ESP) — like Constant Contact — using an @aol.com address as your “from” address, your email will be rejected and recorded as a bounce by any internet service provider (ISP) that checks it against AOL’s new authentication policy. This list of ISPs currently includes AOL, Yahoo, Gmail, Hotmail, and Comcast.
(Note: All email service providers are impacted by this change; it is not isolated to Constant Contact.)
Here’s how can you ensure your emails get delivered
Constant Contact recommends that you refrain from using an @aol.com (and @yahoo.com) address as your “from” address. Instead, choose a “from” address that is associated with a domain you control rather than a free domain (e.g., firstname.lastname@example.org rather than email@example.com). This not only limits any deliverability issues, it also gives your business the legitimate exposure it deserves.
If you have no other choice than to use a free webmail domain (e.g., Gmail, Hotmail), then at least be sure to avoid AOL and Yahoo at this time.
