An awesome tool for sales outreach
I have loved Mystrika since day one of purchase and my only complaint was their UI.
In their latest version they really revamped a sleek, user-friendly UI overhaul. Amazing work.
The Community Prompt AI writer crafts highly personalized emails for each lead, which I absolutely love. As a true 360° solution—including built‑in email warm‑up and scheduling—it covers every aspect of cold‑email campaigns.
Five tacos all the way. Highly recommended for anyone serious about cold outreach!

After I left a negative review (which I’ve since deleted), you BLOCKED my ESP completely???
YOU BLOCKED my email-Service-Provider!!! i want refund mail to Appsumo support is ready.
if i try to create an email in mystryka i get a error:
"Error
This Email Service Provider (ESP) is not Allowed on Mystrika."
This is not the right way to treat customers! Blocking an entire provider just because someone voiced a complaint is unacceptable.

All messages go to the spam
All messages go to the spam mail, while with the normal sender, go to Inbox, knowing that the email has been heated, and it is done for more than a year. Is there a solution. Thank you.

They are lying - and not supporting my support request (I even wanted to buy more codes)
I can not believe that they refuse to answer my support request. Makes no sense!
This is the worst customer experience in 5 years!
The issue:
I had a support question - and also clearly wrote that once they answer this question, I intent to buy one more code (or more) to try out the AI sentiment analysis.
I reached out to them via different email addresses, as I _never_ ever got a human answer from Mystrika. Not even once. One email provider I used was the largest German email provider, the second one was my 5 year long existing gmail account.
As I never received any meaningful help/ answer from Mystrika/ their parent company LLC - I started to write my complaints in the support forum here on Appsumo.
Here - they did not only continue to NOT help, but also I caught them lying:
I wrote, among other messages, here on AppSumo:
"Mainly send you emails. There were never helpful replies to my support emails:
Can you please confirm?! Proof:
30. JAN to: contact@fresent.com (no response)
27. JAN 2025 to: contact@mystrika.com (no response)
20. JAN 2025 to: contact@mystrika.com (no response)"
They responded:
"Hi Jeff,
Like we mentioned before. All emails sent from your smtp server are getting rejected because your sending server is listed on spamhaus.
It does not matter which email id of ours you are sending email to, as long as your sending email server remains listed on major blacklist provider like spamhaus, those emails will never get delivered.
Please use an alternative email id of yours to send"
---
NOW - this is clearly a lie - or an error on their part - as I used the largest public email provider from an EU country without any previous problems before for most of my unanswered support request emails. AND at least one of my emails I sent from my gmail account - also here no answer.
So they are clearly lying in my opinion - they are simply not interested to support/ help.
I therefore demand a refund! This is seriously not funny!
PS: Also super sad because it could have been completely different story. But all this took so long - over 6 weeks !! - so now the second Mystrika code became much more expensive, too. WTF!
This is an additional bummer (that I did not even mention in my support requests - but it sucks, too!)
Now - what? Why are they refusing to even answer my support email(s)?
Worst customer experience ;(
