RE: Inbound marketing with external hosted form is not working
Hi Michael,
I tested an inbound campaign customer journey, follow the screenshot in doc,
and it took 8h that my test contacts received their emails successfully.
After the customer journey went live for a few minutes, I made registration.
Here are my test background:
- My timezone is UTC+8.
- My successful customer journey and its KPIs, you can see the start date is 7/16 9:45 PM

- Informations in General tab:

I registered 2 new contacts from my marketing form. ( One with Yandex, one with Foxmail(Tencent) )
- Foxmail receiving time: 7/17 5:47 AM.

- Yandex receiving time: 7/17 0:47 AM. (Moscow is UTC+3)

- My form hosting site:
https://d365mk.000webhostapp.com/
- My email sending domain:
default onmicrosoft.com
Since you are sending email with your own domain, hence you could check your email server configuration whether there is something impacts deliverability.
Regards,
