"Provide more detailed insights"
4/5
What do you like best about Mailcastr?

It works with Gmail; it puts a basic notification feature which lets me know whether the recipient has opened my email or not. It has been especially useful when it comes to checking on the clients and confirming whether they have noted the proposals provided to them. Review collected by and hosted on G2.com.

What do you dislike about Mailcastr?

What Mailcastr does not factor into the open rate is whether the person is actually clicking on a particular link within the email. This can be frustrating. Review collected by and hosted on G2.com.

"Improved my communication effectiveness"
4/5
What do you like best about Mailcastr?

For myself I liked the feature of tracking when the email is in the inbox of the user. Knowing that I can actually see when the recipient opened my email is pretty powerful. It is suitable for follow-up moves and measuring the response of recipients. Review collected by and hosted on G2.com.

What do you dislike about Mailcastr?

Mailcastr only captures the opens in fluent within the Gmail. This is a major disadvantageous to me since I mainly deal with my clients and co-workers who are using other email service such as Outlook or Yahoo. Review collected by and hosted on G2.com.
