95% of the one to one emails I send through HubSpot come back undeliverable because possible spam content was detected. There is nothing but personally written text in the emails. No template. No mass emails. It is not my domain or host, because when I send the same email to the same email addresses OUTSIDE of Hubspot, using Outlook, they go through fine. All settings with my host are fine, and the domain is on no blocklists. This is making HubSport unusable for my purposes. Others I’ve talked to have had the same issues. Does anyone know why this is happening and how I can send one to one emails through HubSpot successfully? (I’ve turned tracking off btw, so that’s not the problem).
Can you please share the screenshot, so that i can identify the exact problem your facing.
Thanks!
Deepak
