# Warming Up New Email Addresses

You can use tools to ["warm up"](/email-best-practices/warming-up-new-email-addresses.md) new email accounts to boost deliverability by using [Warmbox](https://www.warmbox.ai/?fpr=hyperscale) or [Inbox Warmup](https://app.warmupinbox.com/signup?code=4yLVD6Yeb).

Warm-ups will start sending emails on your behalf to dummy inboxes. Then those dummy inboxes will reply to those emails, creating a feeling of valid emails occurring from your email address.

Generally, it's best to slowly ramp up sending activity yourself rather than use a 3rd party service. This means sending 5-10 emails/day from a brand new domain/sub-domain and slowly increasing volume towards 50-100/day after 3-6 months.
