Get new domains and subdomains ready for sending
Having no email history impacts your ability to send mass emails. By warming up those domains gradually over time, you give ISPs the opportunity to build trust with your various domains. This process will allow you to reach the inbox more successfully, regardless of where you’re sending emails from.
Solve spam placement and other deliverability issues
Even when you’ve done everything correctly with your email campaigns, other factors can still impact your email deliverability. These include domain age, history, past behaviors, and more.
In other words, your email campaigns can be on point, but your past can still haunt you.
Email warmup tools support you with this by consistently giving your reputation a boost over time. The time needed to repair a damaged reputation can vary, but you will see improvements to inbox placement by allowing an email warmup tool to work continuously over months.
Warmy.io is an email warmup service that helps businesses improve their email deliverability and sender reputation by increasing the volume of emails sent from a domain over time.
