Frequently Asked Questions

What is Herald Engine?
Herald Engine is an all-in-one cold email outreach platform. It helps you build lead lists, verify emails, and launch personalized drip campaigns to grow your business.
Can I use my own email accounts?
Yes. Connect Gmail (OAuth), Outlook (OAuth), or any custom SMTP/IMAP provider. You can attach as many accounts as your plan allows and distribute sends across them automatically.
How does email warmup work?
Our 21-day automated warmup gradually increases your sending volume from 5 to 50 emails per day, building your sender reputation before you launch real campaigns. Accounts must be warmed for at least 3 days before use.
What happens after my trial ends?
After your 14-day free trial, choose a plan that fits your needs. If you don't subscribe, your account is paused — no data is deleted. You can reactivate anytime by choosing a plan.
Can I cancel anytime?
Yes. All plans are month-to-month with no contracts. Cancel from your billing settings at any time. Annual plans can be cancelled with a prorated refund.
Do you offer annual billing?
Yes. Pay annually and save — get 2 months free on any plan. That's up to 17% off the monthly price.
