What is Bounce Handling?
When an email cannot be delivered to a recipient, the email server returns a “bounce” notification. QuillCRM Pro automatically captures these notifications and updates your contact records accordingly, preventing future delivery attempts to invalid addresses.
Why is it Important?
| Benefit | Description |
|---|---|
| Protect Sender Reputation | High bounce rates can damage your domain’s reputation with ISPs |
| Improve Deliverability | Clean lists lead to better inbox placement |
| Save Resources | Stop wasting resources sending to invalid addresses |
| Compliance | Maintain list hygiene for email marketing best practices |
Prerequisites
Before setting up bounce handling, ensure you have:
- QuillCRM Pro activated
- An account with a supported email service provider
- Admin access to your email provider’s dashboard
- Your WordPress site accessible via HTTPS (recommended)
Understanding Bounces
Types of Bounces
| Type | Description | Action Taken |
|---|---|---|
| Hard Bounce | Permanent delivery failure (invalid email, domain doesn’t exist) | Contact immediately marked as “Bounced” |
| Soft Bounce | Temporary delivery failure (mailbox full, server down) | Tracked; converted to hard bounce after 3 occurrences |
Soft Bounce Threshold
By default, QuillCRM converts a soft bounce to a hard bounce after 3 consecutive soft bounces.
