"Cleanest product I tried"
4.5/5
What do you like best about Mailstrom?

I liked that it handled multiple email boxes and you could open one email from a batch ready to delete to see the contents. You can also undelete if you need to.

I also like that there is an affiliate program. Review collected by and hosted on G2.com.

"Save me from the deluge of emails."
4/5
What do you like best about Mailstrom?

It helps me clean about 200+ email per day in a matter of moments. Review collected by and hosted on G2.com.

What do you dislike about Mailstrom?

While I get everything isn't free, I personally use a lot of emails. Basically, every element of my life has an email address associated with it. Under their current plan, I can only add some of my emails. I get that someone could add other people to it and get away with it, but these are all my own PERSONAL addresses. I'd love to clean them all. Review collected by and hosted on G2.com.

"Focuses on what truly matters for business"
4.5/5
What do you like best about Mailstrom?

Maelstrom is an amazing tool for someone like me who heavily relies on emails in all aspects of my life. The absence of AI features is a drawback. The short free trial provides a glimpse into its potential. Review collected by and hosted on G2.com.

What do you dislike about Mailstrom?

Mailstroms AI filtering capabilities are unreliable which leads to emails being mistakenly categorized or blocked. Review collected by and hosted on G2.com.

It was quite easy to sign up and use mailstrom.

I manage to remove thousands of unneeded emails with this while this was free. Review collected by and hosted on G2.com.

Now the free trial is quite limited. As a small business, it is bit expensive for me. But for larger organisations, it is very affordable. Review collected by and hosted on G2.com.

"Mailstrom Works, For A Price"
4/5
What do you like best about Mailstrom?

Mailstrom made quick work out of clearing and sorting my Gmail. But, I fear, I waited too long to try such a great product. I had over 150,000 unread emails to ingest. To really get a good sense of what Mailstrom could do for me, I would need to sign for a $59.95 / year account. I particularly liked the Unsubscribe feature. This option, alone, saved me much time and effort. Review collected by and hosted on G2.com.

What do you dislike about Mailstrom?

The free trial only allows one to sort the latest 5000 AND only 3 days to do so. I believe the trial should be extended to 1 week PLUS 25,000 emails to get a better understanding of what the product could do. IF, a second, extended trial was available, I would enjoy using Mailstrom again. Review collected by and hosted on G2.com.
