What is email warmup tool?
An email warmup tool helps you build trust and reputation with email providers, like Gmail or Outlook, when you start sending emails from a new or dormant email address.

When you use a new email address to send a large number of emails right away, it mostly trigger spam filters, causing your emails to land in the recipients' spam folder. To avoid this, email warmup tools gradually increase the number of emails you send over a period of time. This process allows email providers to recognize your address as legitimate and not spammy.

In simple terms, it's like introducing yourself slowly to email providers instead of bombarding them with emails right from the beginning. This way, your emails are more likely to reach the recipients' inboxes, improving your chances of successful communication.
Why do I need an email warmup tool?
An email warmup tool is essential because it helps you build a positive reputation for your email address and domain with email service providers (ESPs) like Gmail, Yahoo, or Outlook. When you send emails from a new or dormant account or start sending high volumes of emails suddenly, it might trigger spam filters and make your messages land in recipients' spam folder instead of their primary inbox.

An email warmup tool gradually increases your sending volume over time, allowing ESPs to recognize your emails as legitimate and trustworthy. By establishing a good sender reputation, your emails are more likely to reach the intended recipients' main inbox, increasing the chance of engagement and successful communication with your audience.
