# Email Bounces & Complaints.

Send With SES handles email bounces, complaints, and unsubscribes out of the box.

**Bounces:** When an email you send cannot be delivered to the recipient, it results in 'bounce'. Send With SES flags such email id's and will no longer deliver emails to these id's. AWS SES expects **bounce rates** to remain below 5%. Senders with a **bounce rate** exceeding 10% risk a sending pause and/or complete ban. 

**Complaints:** When the recipient of your email marks your email as spam, it is treated as a 'complaint'. Send With SES flags such email id's and will no longer deliver emails to these id's. AWS SES expects **complaint rates** to remain below 0.1%. Senders with a **complaint rate** exceeding 0.5% risk a sending pause and/or complete ban.

**Unsubscribes:** When a recipient of your email no longer wants to receive your email, he can unsubscribe and will no longer receive your emails. A high unsubscribe rate is a strong indicator you are sending unsolicited email (spam).

**IMPORTANT:** If your bounce/complaint rates are over the permissible limits, AWS SES will place a pause or complete ban on your ability to send further emails. In such cases you will need to follow up with AWS to lift such bans. Send With SES cannot help you in this regard.

Notwithstanding the limits imposed by AWS SES, Send With SES monitors your sending reputation in real time and will ban your account if your SBUR (Spam + Bounce + Unsubscribe + Reject) rate is >=5%
