What are you using to measure deliverability? One thing I would check is that you're not accidentally filtering data that should be included. Another thing to consider, too, is the timing of when you turned activity filtering on and off. There's a variable there that you'll also want to consider. Is...

In the past, I've used a Program Member Custom Field (PMCF) for this and then created a smart campaign that uses the {{system.dateTime}} token to drop in the value for when the form was submitted. If you set the smart campaign only to allow a person to run through it once, you prevent multiple submi...

Are your forms set up to monitor for bot/spam submissions -- either through a honeypot field or ReCaptcha? While bots won't account for all suspicious submissions, it's a place to start. When you look at the records for the mystery submissions, is there anything in the user record that could indica...

I would be careful about using opens to determine whether or not someone receives another email. With MPP or other similar systems, opens might be artificially triggered even if they didn't open your email. And, if readers have images or tracking turned off, the pixel may not load at all, even if t...

Just to get some clarification, do you have a partition set up for each of your brands in addition to your multiple workspaces? More info on workspaces and partitions

In the Admin section, you are able to set up global form validation rules if you want to block certain domains from filling out your forms. You can also exclude certain forms from those rules if you want.

Your fields are Program Member Custom Fields. These are not allowed in Global Forms as there's no way to tie them to a specific program. More info on PMCF.

Totally agree with @Katja_Keesom here. Duplicates, even intentional ones, can get out of hand very quickly, and you'll run into a lot of issues that might be hard to predict. If there's a way around it, even if it's a pain to set up at the beginning, you'll be happy you did it in the long run.

The aggregate analytics reports will retain this information, which is why you see it on the performance reports. It's just not available in the lead/person record for you to use this information in Smart Lists or other filters. Moving forward, you might consider creating a smart campaign that will ...

In the screenshot you provided, it looks like you sent the email back in February. If this is the case, the "sent email" data on a person's record may no longer be available in Marketo, as that data is retained only for 90 days. The aggregate data in your email performance report won't change, howev...
