Juicebox takes measures to prevent emails being tagged as spam. For example – limiting the maximum number of emails sent per day, delay between every email sent, among others.

Preventing Emails from Being Marked as Spam

Juicebox takes several measures to reduce the likelihood of emails being flagged as spam — such as limiting the number of emails sent per day and adding delays between each message.

1. Limit the Number of Emails Sent per Day

  • For new email domains, start with a limit of 25–50 emails/day

  • For established domains, we recommend a maximum of 100 emails/day

2. Enable “Strict Mode” in Your Account

  • Navigate to Account Settings > Email and Mailbox > Strict Mode. (linked here)

3. Set Up Email Authentication Records

Make sure your domain is correctly configured with:

  • SPF

  • DKIM

  • DMARC

4. Include an “Unsubscribe” Link

Every email sequence should include a clear opt-out link. This improves deliverability and keeps you compliant with anti-spam laws.
