Hey guys! hope you all doing good! I got this question about message composing speed, am trying to work on a Mailer(PHP software). and I just wanted to know if theres a relation between Message composing speed and deliverability.? I mean in the processing.. say you got 10k email address! would it be better to compose message for a small batches of the list. like it compose the email for 5 subscribers then the next 5 and so one! or just take the whole list and compose the email for 10k directly! Or its the same thing ? Thank you so much for your time and happy new year!
