  • (2022-03-07) Michel van Zelst: Doesn't work.
  • (2020-09-17) Kai Jasinski: "Your free trial expires today" popup spam
  • (2020-04-16) 김태민: Nothing. Why is this
  • (2020-03-30) Dr. Shakeel Ahmad Mir: Does not work on my android 9 device and win 7 PC. Repeatedly asks for gmail log in, but without any success. Used to work earlier on my phone.
  • (2020-03-11) eleno deleon: I can't remove the addon from my Gmail account. I've uninstalled the chrome extension, and tried to uninstall the addon using G Suite Marketplace, but the add-on is not found. As a result, the add-on still shows in my Gmail addon sidebar and has not not disappeared for over a week now.
  • (2019-09-05) Steve Riley: I bought this as an LTO for $59 for lifetime access. Unfortunately there is no real way to test it until you buy it. I'm no longer using it because it lacks the basic functionality that other trackers have. You can not send and archive at the same time or BCC to a CRM with a click like you can with Yesware. Also, the read icons don't show up as they say that they do in the video. Total waste of money.

  • (2019-08-30) Sukumaran KB: Fantastic and Simple, does exactly what it says. You get notified when people read your messages and how many times they've read your message.
  • (2019-08-09) Paulo Bud: I need help. It is not working for me. Whether the icon is red or green, most of the messages are not tracked. I believe green means tracking, but after sending it, the message does not show as tracked on the dashboard. Only a few does. And I am not sending more than 5 per day. Update (Aug 2019) They emailed me this: [Try the new version] "If it works for you, please update your chrome store review with a 5-star rating and I'll personally extend your account validity to 1 year for free!". When I emailed back saying I would try it, they sent me a message offering a paid plan, and I never got anything for free.

  • (2021-12-08, v:3.6.13) Samantha Moore: Branding on paid account
    I have a paid account that has suddenly been adding branding to all my emails including my personal account which is only connected to my work email account (the one Mailcastr is with) through Google to be logged in simultaneously but isn't associated with my Mailcastr account. It allows me to highlight and delete the branding but if I click the x to remove it asks me to upgrade to the account I already pay for. I removed and added back the browser extension, confirmed our plan on my account page, and even clicked upgrade to see what it would say and it has the current plan we pay for selected as what we have yet it still says upgrade to it. I tried numerous times to contact the company through the help page, but it takes me to an error page saying I've been restricted from accessing this helpdesk page. Please fix this so my account shows up properly and I don't have to remove the branding from every email I send. The tracking also counts me clicking my own sent emails as a time it was opened which is confusing when I do sometimes need to look back at sent mail but if I don't keep track of any times I've opened it myself then I have no way of knowing if the other person opened it also. If the issues can't be resolved I'd like a refund and to fully cancel, although at this point after having such a difficult time contacting the company I'm not sure I want to keep this anyway. I'd like to be contacted about this, thanks.
  • (2021-10-18, v:3.6.13) Viviane Cristine Silva: Cannot remove it from my Gmail Account
    After removing this extension from Chrome and Gmail, the Mailcastr ICON remains in my Gmail Dashboard. I would also remove my account from that company, but there is no option to remove the account in their website. So far, no reply, no solution to this problem.

  • (2020-10-13, v:3.6.5) Elizabeth Firnschild: Billingg
    I have tried to contact this company thru the online support. When I submit my ticket I get a screen that indicates that there is limited support for this page. I have chatted and emailed there support and the emails have not been opened after 5 days. They charged my PayPall account twice and I am still in the free trial period. PayPal have informed my that I need to contact the vendor or my bank my bank has indicated I need to contact the vendor and the vendor does not reply. I am out $72.00 Do not use this service. Everyone Calendly but this is not a good company.
