Unique Opened Vs Open by Location

Unique Opened Vs Open by Location


Hello Support

I have a mailing list with 81 contacts, RIGHT.

When today check the statics i see this numbers.

Emails sents = 81 (Right)

Unique Opened = 36 (44% Right)

BUT .. in "EMAIL OPEN BY LOCATION" i see:

Country 1: 58 Opened

Country 2: 3 Opened

Q:

What is the difference between "Unique Opened"(36) and "Open by Location" (58+3)

Thanks
