They leave work without giving me help.

Your time is precious. Share my few days of tier 3 experience.

Service first
I am unhappy with their service. The reason is that they don't help while they're empowered. For dns modification to be completed, other services allow the user to decide. However, in mdirector, when approval is completed. Modified the sender or made the landing page domain available.
I've asked them countless times after dns modification but I'm only active on apsumo and don't send emails. And They are going home.

Second, interface

If you look at their interface, you will experience Windows 95. It's uncomfortable and slow, it's very underperforming compared to the recent droog-and-drop method, and the finished mail is not pretty. The number of templates is also very small.

Third, my letter is a spam box

The important thing in email marketing is that my email doesn't go to the spam box. But my mail goes straight to the spam box. I've used a lot of email marketing, but this one lets me move to the awesome spam box.

It's not about getting off work. You should be business partners.

Other places offer 24-hour service. If there is a problem, it will help me with my business. But you don't care about my problems. Just tell me to resend my email because it hasn't arrived.

Why don't you guys take my questions when other services take questions by email? Why doesn't the service run QnA bulletins as a ticket instead of emails?

I've been doing email marketing for years, but service, spam, DNS permissions, etc. I've never seen a place like this before.

Lastly

They are cheap. That's the only advantage.

Your time is precious. I recommend that you look for other services.
