Ongoing Yahoo delays

I’ve been hearing from folks over the last few days that they’re seeing an uptick in deferrals from Yahoo! The deferrals are not uniform. ESPs report they’re seeing some, but not all, customers affected. Other ESPs aren’t seeing any changes. It’s not just you. But it would be very worthwhile to dig into engagement and […]

Happy July! We are back from another wonderful M3AAWG conference and enjoyed seeing many of you in Dublin. It’s always so great for us to connect with our friends, colleagues, and readers in person.

    I've been hearing from folks over the last few days that they're seeing an uptick in deferrals from Yahoo! The deferrals are not uniform.
