E-mails in retry queue and spam folders

E-mails in retry queue and spam folders

Hello, 

Recently I've noticed more and more emails are landing in retry queues and not seeming to send (with the green tick verification). My e-mails are also landing in spam folders of people i've had regular contact with, so this shouldn't be happening. Naturally for a business e-mail this is very frustrating. 

Could someone please help?

Thank you
