Outreach emails not sending

Updated June 3, 2026 · By Sophia Miller

If your outreach is not going out, it is nearly always the email connection or a sending limit. Here is how to find and fix the cause.

Check your email connection

Go to Settings > Integrations > Email and confirm your account still shows as connected. Connections can drop if you changed your email password or revoked access. Reconnect and try sending again.

Check sending limits

Email providers cap how many messages you can send per day. If you are sending a large batch, you may have hit your provider's daily limit, not a KALO IQ limit. Spread large sends across a couple of days, which also protects your sender reputation.

Check authentication

If your emails send but land in spam, your domain authentication may need work. Setting up SPF and DKIM for your sending domain lifts deliverability sharply. If you are not sure how, your IT team or email provider can set these up quickly.

Frequently asked questions

Your email connection most likely dropped, often after a password change. Reconnect it under Settings > Integrations > Email.
