Do I have to warm up the IPs before sending the campaigns?

If you need to send a very high number of emails, it may be necessary to warm up the IPs, to get better delivery rates.
This is only necessary for very advanced users, sending a lot of emails per month.
But if you need help about this, or would like to know about our dedicated IP plans, contact us and our technical staff will help you out:
