When I’m sending email to potential customers, I’d love to know more whether they open it and when as well as clickthroughs. Is there a free/cheap tool that does this? Can I just copy an image link from Mailchimp or Google Analytics or something?
I have Signals by Hubspot for my personal gmail account, and something like that is what I’m looking for. However, I am using Office365 (Would like to switch, but that’s not happening right now) for my business account.
