If you go to Analytics and see a 100% open rate, do not worry and check the possible reasons below:
If you have deleted leads from your campaign at any point, you could be seeing stats for these deleted leads as well
If you are viewing the analytics for only a specific date range (like a week). It reports the sent and opens within that specific time frame
If someone was sent an email before that week and opens the email in that selected time window, that's when the analytics event will be counted.
If older leads open their emails during this selected time window, they will also be counted.
If you're viewing this on the Analytics Page for all campaigns, instead of a single campaign.
If you hover on the 'i' information icon next to the open rate, it will show you the open rate by lead and by volume.
By volume: how many of the emails sent were opened.
By lead: X unique number of people opened the emails.
