Mailwarm helps you build trust fast, protect your main domain, and get replies early so your first outbound engine actually works instead of landing in spam.
Each interaction creates multiple positive signals that boost your sender reputation and improve deliverability.
Your email gets marked as non-spam. If it comes directly into the spam folder, it will be put in the inbox, which is a positive signal!
Your email gets opened and read. This increases your opening rate which raises your positive activity!
Your email gets an important tag, starred and marked as primary. This results in a positive point for your account.
You'll get replies according to the reply rate you've set on the platform. This increases your IP reputation!
An email is sent from your SMTP to one (out of thousands) Mailwarm email address. This improves your global bounce rate!
