Email Manager

Email Manager shows the individual email addresses inside a selected list. You can filter by subscribed, unsubscribed, inactive, or verification result status directly from the Email List Manager badges.

Each address entry shows the name (if provided), subscription status, verification result and the date added. Individual addresses can be edited or deleted from the action dropdown.

Import Emails

Import Emails lets you bulk-add subscribers into any email list from a text input or a CSV file.

Importing via text

Paste email addresses into the Email Addresses field, one per line. If you have a name, add it after a comma:

smithpatrick@gmail.com,Smith Patrick
kellythomas@yahoo.com,Kelly Thomas
johnjames@live.com,
jean4u@gmail.com,Jean Alwin

Importing via CSV

Upload a .csv file using the Email Addresses CSV File field. Click Sample CSV File to download the correct format.

After selecting the Email List and supplying the data, click Proceed to import. An import summary reports the count of Valid, Invalid and Duplicate addresses processed.

Email Verification Center

The Email Verification Center validates email addresses in a list against an email API provider before sending, so you only send to deliverable addresses.

How to Verify

1. Select the Email List to verify
2. Select the Email API Provider (an Elastic Email identity with API enabled)
3. Set the Email Limit — the maximum number of addresses to verify in one run (default: 50)
4. Click Start Verification

A live console streams verification output as each address is checked. Click Stop to pause at any time.

Each address is classified as one of:

• Valid – Address exists and accepts mail
• Invalid – Address does not exist or is undeliverable
• Risky – Address exists but has a high bounce risk
• CatchAll – Domain accepts all mail; deliverability uncertain
• Unknown – Could not be determined

After verification, the result for each address is saved and appears in the Email List Manager badges. Use the Email Verification Filter in the Newsletter Manager to target only the addresses with verification results you trust.

Generate Subscribe Code

Generate Subscribe Code creates an embeddable subscribe form that you can add to any external website or page, allowing visitors to join your email list directly.

Generating a Subscribe Code

1. Select the Email List subscribers will be added to
2. Select the Language for the form labels
3. Enter a Source tag to identify where subscribers came from (e.g. website, blog, landing-page)
4. Set the form Width in pixels (default: 500)
5. Set the form Height in pixels (default: 230)
6. Click Generate

The output provides:

• An iframe embed code to paste into any HTML page
• A direct subscribe form URL for linking or testing

Cron Command

The Cron Command section (admin only) provides the command to automate newsletter delivery. Add the command to your server’s crontab to send scheduled newsletters without manual intervention.

Access it via Admin Panel → Newsletter Plugin → Cron Command to get the exact path pre-filled for your installation.

A typical daily cron entry looks like:

0 * * * * php /path/to/seopanel/plugins/newsletter/cron.php

Adjust the schedule pattern to match how frequently you want newsletters to be dispatched.

• Allow user to access system email server – When enabled, non-admin users can use the system-level email server for sending
• Newsletter content wordwrap length – The character width at which newsletter plain-text content wraps (default: 70)
