Email marketing is all about expectations, and it’s up to you to set them. If your call to action is strong, and your follow-up is consistent, then you can count on a positive campaign. However, if you promise to send one email per week and instead send them daily, then you’re setting yourself up for failure. On the contrary, if someone is expecting daily updates or critical product updates and you don’t’ deliver, then they are likely to be just as upset in that case too.
As of mid-2016 email deliverability is still an issue for legitimate marketers. According to the report, legitimate email servers averaged a delivery rate of 73% in the U.S.; six percent were filtered as spam, and 22% were missing. This lags behind other countries: Australia delivers at 90%, Canada at 89%, Britain at 88%, France at 84%, Germany at 80% and Brazil at 79%.[7] 

If links and looks are set, begin interacting with the page. Abandon it, adjust the window size, convert. Are error messages appearing when they’re supposed to (if, for example, you don’t input all the form’s required info)? Is your CTA button working? If you abandon the page, are you retargeted with ads? When you resize the window, does your landing page respond accordingly?
