The only thing i can think offhand is the following

1 -  Try reconnecting / recreating the email account on the device

2 - Ensure you have no filtering / parental controls on the Deco as this can stop email if configured sometimes.   THis is quite a common one

@Philbert thanks for the reply. 
I havevtried deleting and reinstalling the email. 
there aren't any filters or parental controls on at all- no kids in the house. 
many other ideas?

thanks

Switch your Deco mesh to Access Point mode to see if problem will go away.

@Alexandre. Thank you.

This seemed to work for that particular email, but unfortunately, it meant that noting else seemed to work properly-Netflix wouldn't pick up anything, no other websites could be used or email accessed.

Any other suggestions would be wonderful!

Thank you

When Deco mesh runs in Access Point mode, it only provides WiFi signal. The network is managed by your ISP router. Meaning: issues with accessing Netflix or websites are extremely unlikely to be caused by Deco mesh running in Access Point mode.

Power off all Deco you have, enable WiFi on your ISP router and see if problems go away. If they really do, perhaps you should consider returning Deco units and try with different brand of WiFi mesh.
