IP Warm-up to increase deliverability

Warming up an IP address means gradually increasing the volume of good quality email sent to establish a good sending reputation.
When an ISP receives an unexpected volume from a new address, or one that usually sends only a few, it begins to evaluate subsequent traffic more carefully.
The Utixo SMTP service uses this technique to allow for faster sending speed and delivery reliability.
