A very tidy email solution

I have been a gmail user ever since the Beta launch and i have always managed my account through the browser, using the ActiveInbox plugin for many years. However, I felt that I no longer wanted to manage email in the browser. It is far too easy to be distracted by other tabs and loose focus. So I tried various stand alone email clients, including trial perios of paid for solutions. But non of them seemed to suit me.
That was when I decided to give Spark a go and I am so grateful that I did. I can manage not only my gmail account but three other blog accounts seperately with ease within the environment. Previously I was forwarding the other accounts to my main one which wasn't ideal.
I can easily set up a system that suits me and pin organisation folders to the sidebar as well as being able to easily forward content to Evernote and other applications. I think Spark holds up very well in amongst the premium clients, but I am grateful it is free because I am currently not in a position to be able to pay for it!

Could be 10 stars if not for a few bugs

Firstly I never write these but I am doing it because I love SPARK so much I hope they read it and fix the bugs/issues I am facing for my company. 1. We are a creative business and get automated emails sent by Klaviyo for us to preview, these emails populate a random name to preview, as if we are the customer. Sadly SPARK after 2 emails has decided to nickname our team by these incorrect names. Michelle is now Sue Anne!!! Which is confusing to search, add to calendar and just weird! Myself and another team member were both on one email and SPARK has now grouped us together as the same person on search, very annoying as ALL my emails come up everytime I search a email from this certain team member. 2. I have many email accounts and when I read something on my phone it oftern flicks to the other one of my accounts, without me noticing and sends it from there with that signtaure which is annoying and when I am meant to be sending the email. 3. The Calendar doesnt scroll by month on a monitor 2. changing the times of meetings is slow. 4. you can't have your calendar and emails open at the same time by opening another window. Annoying again. However theres so much I LOVE about it. Pls fix these things!!!

Problems with update

I’ve been using Spark as my email client of choice for some time now on both my Mac and iPhone and never had any issues. Since the update to version 2.0 I’ve had nothing but problems. Snooze doesn’t work, emails appear back in the inbox within minutes rendering the feeature useless. For now I’m having to keep all my emails in my inbox until a fix comes in a future update (hopefully). The folder count is inaccurate, at the moment all my folders show 1 more email added to the count than they actually have. There’s me checking my folders to see if there’s an extra email in there and all the time it’s the inaccurate count. The count across all folders also changes whenever I action an email, I can read, delete, mark as spam, etc. and the count on all my folders changes to random numbers and then settles back the correct count (plus an extra one) after a few seconds. There seems to be some sync issue too. I had half a dozen emails that I moved to a folder on my Mac, but they still showed in the inbox on my iPhone and they wouldn’t budge. Manually moved them on my iPhone and haven’t seen an occurence of that issue yet, but I’ll keep an eye on it. All these issues have been submitted to the developer so let’s hope they get resolved.
