FAQ – Email Warm-up

1. Why should I warm up email accounts?

Email Warm-up automatically creates a positive email history for your account to improve its sender reputation. The better your sender reputation, the more likely your emails are to land in the Inbox instead of spam.

2. How does warm-up work?

When you start a warm-up, your email account joins a warm-up network. It will automatically send and receive emails from other real users and our system mailboxes.

3. What email accounts can I warm up? What providers are supported?

You can warm up any email account in Snov.io and the warm-up effect is guaranteed. It works with any email provider, including popular services or specialized SMTP hosts. You can also run a targeted warm-up to raise your reputation with specific providers you select.

To start a warm-up, connect your account to Snov.io.

4. Which Snov.io plan includes warm-up?

Email Warm-up is included in every Snov.io plan. You can try it even on the free plan.

5. How many email accounts can I warm up?

Every plan includes warm-up slots. On Pro plans, you can warm up an unlimited number of accounts simultaneously. Higher-tier plans offer higher warm-up limits per account.

During the warm-up, your email accounts can send a certain number of emails per day. Your warm-up slots depend on your plan. On Pro plans, you get the unlimited warm-up slots. The number of warm-up slots means how many email accounts you can warm up at the same time.

6. Can I send email campaigns and warm-up accounts at the same time?

The best practice is to warm up accounts before launching campaigns or to pause your campaigns and do the warm-up period. This will ensure optimal warm-up results and improved deliverability for your campaigns when you start them.

The warm-up’s duration depends on your email's current condition when you start warm-up.

• at least 4 weeks for newly created mailboxes;
• at least 2 weeks for older accounts with some sending history.

When your campaigns are active, keep the warm-up running but lower its daily limit to 10-20 emails. This helps maintain your sender reputation and ensures you don’t exceed your provider's daily limit.

It's also a good practice to have a few warmed-up mailboxes as backups in case one of your accounts faces deliverability issues. This allows you to switch senders in active campaigns while restoring the reputation of the affected mailbox.

7. Can I use the same schedule for email campaigns and a warm-up?

Yes, it's even better to set a warm-up schedule that matches your usual campaign sending times. This keeps your account within its regular activity timeframe.

8. Do emails sent from the email account during warm-up count towards the daily sending limit?

Warm-up emails are not included in the daily limit (Messages per day) in your email account settings. However, they count toward your email provider's limits for your account.

9. How do I know which emails in my inbox are related to the Snovio warm-up?

You'll see an "snv" tag next to each email sent during warm-up. A "snovio" folder will be created in your inbox to store all warm-up emails.

10. Can I limit the number of emails I receive from other users during warm-up?

The number of emails received is determined by a Reply rate set in the warm-up settings. This means the percentage of your emails that will receive replies by the end of the warm-up process.
