Since April 6, the open rate on our emails has dropped to 2%. The last normal open was on April 4 with 11% open rate. We send out the same eMail format every Sunday at 8 am announcing upcoming workshops. Last Sunday was 11%. Today, from 8 am to 7 pm now, it is still around 1% (480) when in the past, we would reach 1000 opens in the first three hours. We send out roughly four emails a week and I don't see what else we have changed but this week, since the 6th has been a disaster.  Has anyone else seen a change in the open rate?


Hello @Raj.Mashruwala ,


Have you recently increased your number of contacts significantly, that you regularly send to regularly? Or have you noticed contacts that used to have high engagement suddenly not opening your emails? When dealing with such a high number of contacts, I'd recommend looking into some general best practices for deliverability


Deliverability can have a lot of variables, from elements on our side, on your side, on the recipient's side, and in their email system company's side. It's also a generally good idea to set up additional authentication for your emails - whether that's through us if you have a free domain (e.g. Gmail, Yahoo, AOL, etc.) or via self-authentication if you have your own domain (such as through a business or other organization).


If you'd like to learn more about safelisting, and what it entails:


Safelisting domains in a security system


Safelisting email addresses in an email client or security system


If you're wanting more in-depth, specialized insight on your current deliverability, it'd be worth speaking with one of our Deliverability agents.

Thank you for your reply.  We have built our client list gradually over the past 12 years and I add new contacts to it gradually every week.  We have now 35k contacts in our database and we normally send emails to about 25k of them. Every week, we send out 3 to 4 emails announcing our upcoming workshops on Sunday and reminders for the specific workshop coming up in two days. We have made no changes to the subject line or the date and time of the release.  Up to April 4, we were doing well for ourselves at 11-15% open rate. Starting on April 6, the open rate dropped to 2% or less.  At Constant Contact specialist's suggestions, I ran a A/B test on a different day but no improvement in the open rate. We will experiment with the Sender's name, subject line, day and time of day but given the day - April 6 - when the open rates dropped like a rock, we are asking the community if there were any technical changes made by Constant Contact that may explain this.
