📊 Why is the number of emails sent lower than the number of contacts in my segment? – Webmecanik

When you schedule an email send, whether it is a segment email (one-time send) or a campaign email (automated scenario), you may notice a discrepancy between the total number of contacts in your segment and the actual number of emails sent.

This discrepancy is perfectly normal and is the result of several automatic filtering rules applied by Webmecanik Automation to preserve your deliverability.

1. 🚫 Some contacts do not have an email address

A segment includes all records that match your filters (for example: a customer type, a geographic area, or a form source). Some of these records may have been created without an email address (contacts from a phone import, incomplete records, etc.).

Behavior: The system automatically ignores these contacts when sending the email because no destination address is available.
Impact: This rule always applies to both segment emails and campaign emails. The contact is counted in the segment, but no send is triggered for them.

2. 🔕 Some contacts are marked as “Do not contact” (Bounces and Unsubscribes)

Contacts with the “Do not contact” status remain visible in your segments, but are automatically excluded from your marketing email sends:

Unsubscribed contacts: Contacts who clicked an unsubscribe link or were manually deactivated.
Bounced contacts: Addresses that generated a permanent error (hard bounce) or repeated temporary errors (soft bounces).
Impact: Applies to segment emails as well as Marketing campaign emails.

3. 🎯 The campaign email is of type “Marketing” and has already been received

If the send takes place as part of an automated campaign with an email configured as Marketing type:

A contact can receive a marketing email only once.
If a contact in the segment has already received this specific email during a previous send (or in another campaign using the same email), Webmecanik Automation will not send the message to them again.(Conversely, an email configured as Transactional type within a campaign may be delivered multiple times to the same recipient).

💡 Tip: Align the size of your segment with your sends

To obtain a contact count in your segments that more closely matches your actual sends, you can add the following additional filters to your segment configuration:

Email > is not empty
Do not contact (Email) > equals > No
