How does checkmark feature work in Gmail plugin?
There are three variants of the check-mark icon that you usually see in your Gmail inbox where our Gmail plugin is active.
A double checkmark in grey color
Grey double tick denotes that the email was not sent through SalesHandy's Chrome plugin.
This happens when the SalesHandy's Chrome plugin is not activated. Also, for all the Email Campaigns that are sent through SalesHandy's web app, when you try to view them under your Sent folder in Gmail/Gsuite account, you can see the double grey check-marks because the emails are sent directly from the web app and not the Gmail mailbox.
A single checkmark in blue color
A single blue tick with a grey tick denotes that the recipient has received the email but yet to open the email.
A double checkmark in blue color
Blue double tick denotes that the recipient has opened the email.
An exclamation mark denotes the mail is bounced. In this case, please verify the email address of the recipient.
