Manual email warmupⓘ
Want complete control over your warmup emails? We’ll send you our seeds, allowing you to send your emails directly. Then, check your dashboard for your reporting.
The email warmupⓘ tool will send emails from your mailbox to our privately owned seed email addresses. These warmup emails only go to these addresses and are never shared in a network of other users.
Your emails will automatically receive positive engagement, which sends signals to internet and mail service providers that your business emails are quality, not spam. Warmup provides this via:
After enough of these signals are sent, providers will gradually correct how they filter emails from your mailbox. Fewer emails will go to spam, and more will start reaching the inbox.
Sit back and allow the email warmupⓘ tool to work. The duration it takes Warmup to work will vary based on domain age, your desired sending volume, and existing reputation issues.
To gauge your progress, the email warmupⓘ software dashboard conveniently tracks emails sent, charts where those emails land, and calculates your overall inbox deliverability score.
Once Warmup reliably gets your emails to the inbox, your email campaigns will be ready to rock.
