Ever send an email and wonder if the person read it? Was your strategy dependent upon that email being read? For example if they didn’t read it, or if they did read it and didn’t reply, time to move on. What if they read it immediately? Whether an email is read or not and how long it takes to get a reply can be very important information for creating your strategy with that client.
Fortunately there are two very good options for email tracking. Bananatag, which works well with Gmail/G Suite, and Outlook. The other option is MailTag which is limited to Gmail/G Suite. Both offer a free version. Bananatag’s free version is limited to tracking 5 emails a day. MailTag has a more powerful free version, and though it works well, the down side is a “Sent with MailTag” footer. Both options offer paid versions.
