What are your biggest questions about email deliverability?

Hi creators! 

I'm working with our Deliverability Lead, Alyssa, to put together some crazy awesome resources for you all about deliverability. 

So tell me: what are your biggest questions about deliverability? 

They might entail best practices, confusion around how to properly set up your sending address, or a myriad of other things. (We all know that deliverability can be an involved process!) 

Post your top questions in this thread, and I'll use those to create this new deliverability series we're working on. 

Thanks in advance!
