Email warm-up FAQ
Questions, answered.
Setup, warm-up, sending limits, billing and your data. Can't find what you need? Contact us.
Getting started
What is email warming?
A new mailbox has no sending history, so providers treat it with suspicion. Warming sends a small, growing number of emails that get opened and replied to, which builds a reputation before you start a real campaign.
Can I use domains I already own?
Yes. Connect them and we'll check the DNS records and tell you exactly what to change. You can also buy new or aged domains inside the app.
Which email providers do you support?
Mailboxes we create for you are set up and connected automatically. You can also connect existing mailboxes from your own provider.
Do I need to know how DNS works?
No. We set the records for domains you buy through us, and for domains you connect we show exactly what to change. Ask Basil can walk you through it.
Warming and sending
How long until a new mailbox is ready?
About five days. On our standard schedule a new mailbox sends 3 emails on day 1 and 3 more each day after, until it reaches its cold limit of 15 a day on day 5 (day 4 on Starter, where the limit is 10). The warm-up schedule calculator shows it day by day.
How many cold emails can I send?
Up to 15 a day per mailbox on Growth and Scale, and 10 on Starter. Each mailbox sends at most 30 emails a day in total, warm-up included. To send more, add mailboxes rather than pushing one harder.
Do I need to keep warming after I start sending?
We recommend it. Warming keeps running alongside your campaigns, which helps your mailboxes hold their reputation.
What happens if a mailbox gets into trouble?
If warm-up emails start bouncing or placement drops, we slow that mailbox down automatically and tell you what we found.
What are pre-warmed mailboxes?
Mailboxes that have already been through warm-up, so you can start sending the same week. They're $3 each per month.
Plans and billing
Can I change plans later?
Yes, upgrade, downgrade or cancel at any time from Settings. Changes take effect at your next billing date.
What if I need more than Scale?
Add extra mailboxes for $1 each, or contact us about a custom setup.
Do you offer refunds?
We don't refund partial months. If you cancel, your plan stays active until the end of the billing period.
Who needs a dedicated IP?
Teams sending at higher volume who want a reputation no other sender can affect. Dedicated IPs are available on Growth and Scale for $20 a month each.
Privacy and safety
Do you read my emails?
No. Warm-up emails are generated by us and never include your campaign content or contacts. Your campaigns and replies are only processed to send and show them to you.
Will warm-up emails clutter my inbox?
No. They're filtered out of your inbox automatically.
What happens to my data if I leave?
Mailbox credentials are deleted straight away, and the rest of your data within 30 days. See our privacy policy for details.
