Pros & Cons from Real Users

Pros

  • I've been a happy user of Mailbird 2 and I jumped at the chance to buy the lifetime deal. This one-time payment for endless use of their great service seemed like a bargain. Mailbird 2 has been a big help, making my email tasks easier with its simple design and strong features. But things changed with the release of Mailbird 3. This new version, although better and more promising, came with a surprise. The lifetime deal I bought for Mailbird 2 does not cover this upgrade.
  • 1. Reliability in receiving and sending email without duplicating. 2. Send Later allows review time and saves me from sending follow-up emails. 3. Unified Inbox defines by addresses by color. I like to experiment with alternatives and keep coming back to Mailbird.
  • Initially we really liked the platform because it was similar to Apple's Mail program. Initially we really liked the platform because it was similar to Apple's Mail program. Initially we really liked the platform because it was similar to Apple's Mail program.
  • It looks like an intuitive, great, flexible program - if you can use it. The problem is that if you run into any problems whatsoever, there is no meaningful tech support.

Cons

  • It feels like I'm being asked to pay again for Mailbird 3, and that's a letdown. I thought "lifetime" meant that any new versions would be included. But, it looks like I was wrong. I get that making and maintaining new software costs money. But, it's hard to be asked to pay again after buying a lifetime deal.
  • Pricing. I'd also like a way to block or delete by simply listing inbound addy.
  • There's absolutely NO service except for help articles provided on their website. There's no way to call them on the phone and just today even their email was returned by Mailbird saying it's no longer in use, but didn't provide an alternative email. The entire platform is an entire money making scam I believe.
  • If you google these people, there's a tech support phone number. But it doesn't work. The only tech support, even for paid, premium users is by email. Essentially, there is a 2 day turnaround for each question, and most of the time, the question is "answered" by an irrelevant article url. I've been working for over 3 weeks to try to port some large archived email files from Thunderbird, and have received no useful advice. I have medical practice, medicolegal, academic, and personal files for 20 years (16 GB) I can't port.

Pros & Cons from Real Users

Pros

  • With Spike, conventional email is transformed into a chat-like conversational style. Users accustomed to messaging applications will find this method easier to use and more natural when it comes to email conversation.
  • Spike provides us with an environment that facilitates interaction with third parties in different ways, whether by calls, messaging, e-mail, etc. Its platform is intuitive and straightforward; it is pretty easy to understand how it works and to take advantage of its many communicative and collaborative benefits for the benefit of work teams.
  • Spike is an interesting email client which transform your old boring email window to interesting communication interface. It offer amazing collaborative capability which make it it perfect candidate of client with exceptionally useful extra feature contributing to higher conversion.
  • #1- Spike is also supported on mobile platforms. #2- Inbound and outbound emails converted into easy chat interface. #3- Task tracking and organizing are very convenient. #4- Team collaboration is great with its realtime chat.
  • New way to start chatting without sharing your mobile number, so it helps if you have privacy concerns. It has all of the feature that typical email apps have. Also integrated with voice and video calling.

Cons

  • Although Spike offers a mobile app for access while on the move, some users have noted that it occasionally has less functionality than the web version.
  • It is multiplatform, but its application for mobile devices is not as optimal as the computer one; some functions cannot be used.
  • Spike offers many add-on features with no extra cost involved. It's a great tool for email with collaboration. No Cons.
  • #1- We had an overall positive experience with Spike.
  • Till now I didn't faced any serious problems with this tool.
