Here’s something that could happen. It’s showing in the Channels>Emails>My Email that it’s sent 10 emails at a time but it could not be sent at a time like the number increased from 0 to 10 at a time. Maybe the number increased 0 to 10 but it’s sending with the throttle.
Thanks a lot. Some mails are heading to spam. Don’t know the % though. I am using Office365 SMTP. Do you think, warming up and increasing daily up to 5K a day will help heading inbox? Or changing SMTP/ip rotation is needed?
You might as well use a self-hosted mail server (which is my preferred method and also cheaper, at least, for me) or go with a reliable cloud-based SMTP provider e.g SendGrid, MailGun, SES.
This is not needed.
You can send me a p.m if you have a very specific use case.
