Email Quota

Learn what email quota limits apply to accounts.

Humanic regulates email volume in two ways:

1. email volume (quota)

2. sending rate

These limits help improve your deliverability and likelihood of reaching your recipient’s inbox.

​Free Account Daily and Monthly Email Quota

Free accounts have a daily email quota of 100 emails/day and 3,000 emails/month. This quota includes both sent and received emails. Multiple To, CC, or BCC recipients in sent emails count as separate emails towards this quota.

​Paid Plan Email Quota

• Humanic plans have no email quota limits.

• Multiple To, CC, or BCC recipients in sent emails count as separate emails towards the monthly quota.

​Rate Limits

All accounts start with a rate limit of 2 requests per second. The rate limits follow the IETF standard for stating the rate limit in the response header. If you have specific requirements, to request a rate increase send an email to [e-mail]

​Bounce Rate

All accounts must maintain a bounce rate of under 4%. The Metrics page within an account and/or webhooks allow you to monitor your account bounce rates. Maintaining a bounce rate above 4% may result in a temporary pause in sending until the bounce rate is reduced.

Tips to keep a bounce rate low:

• Remove inactive user email addresses from email lists.

• Only send to recipients who have given consent to receive email.

• When testing, avoid sending to fake email addresses.

• If you are using open/click tracking, periodically remove recipients who are not engaging with your emails from your email lists.

​Spam Rate

All accounts must have a spam rate of under 0.08%. The Metrics page within an account and/or webhooks allow you to monitor your account spam rates. Maintaining a spam rate over 0.08% may result in a temporary pause in sending until the spam rate is reduced.

Tips to keep a spam rate low:

• Give recipients an easy way to opt-out of emails.

• Send relevant and timely emails.

• Only send to recipients who have given consent to receive email.
