Q: Can I use a subdomain email address with Mystrika?
Hi,
I'm a small business owner and new to cold outreach. After a bad experience with another tool recently, I just started a free trial to see if your platform is a better fit. I'm looking to use it with the AppSumo LTD.
I was trying to connect my email address, which is on a subdomain, [name]@[subdomain].[domain].com
However, I received this error message: "Subdomains are not allowed for emails".
I was under the impression that using a subdomain is a best practice to protect my main domain's reputation, but as I say, I'm no expert.
Could you please let me know if I'm doing something wrong or if there is a different way to connect my subdomain?
Thanks for your help!

Thanks for your interest in Mystika.
There are two (different worlds) things that are part of email marketing world.
- Subscribed list (Opt-in users, Customers etc)
- Non-subscribed list (Cold Email, Intent based targeting etc)
These two email marketing things are polar opposite of each other, and if mixed can rekt your whole domain and email reputation.
Using (subdomain) as part of sending emails, is a strategy that should/has been be used for subscribed list. Though companies there too are increasingly switching to separate domain.
Subdomain, never was, and never has been a part of Cold Email strategy.
If you create and use subdomain from your main domain, and attempt to send cold email. It will 500% rekt your main domains reputation. Please never do that.
