## FAQ

### Do I need a third-party email service?

No! CN Blog Mailer uses WordPress’s built-in wp_mail() function. However, for better
deliverability with large lists, we recommend using an SMTP plugin like WP Mail 
SMTP.

### How often are newsletters sent?

You can configure the sending frequency in settings. Options include daily, weekly,
bi-weekly, monthly, custom interval, or manual sending only. A background process
runs every 30 minutes to ensure newsletters are sent reliably even on low-traffic
sites.

### Can I customize the email template?

Yes! You can customize the email template including colors, fonts, and content length.

### Is there a subscriber limit?

No, there are no subscriber limits. The plugin includes a reliable queue system 
to handle subscriber lists of any size.

However, for large subscriber lists (1,000+), we recommend:
 * Using an SMTP service(
like SendGrid, Mailgun, or Amazon SES) instead of your hosting’s mail server for
better deliverability * Monitoring your sending reputation and bounce rates * Ensuring
your server has adequate resources to process large batches

### How do subscribers unsubscribe?

Every email includes an automatic unsubscribe link. Subscribers can opt-out with
one click.

### Is it GDPR compliant?

Yes! The plugin includes:
 * Clear consent during subscription * Easy unsubscribe
process * Complete data deletion on uninstall (if configured) * No data sent to 
third parties

### What happens to my data if I delete the plugin?

You can configure whether to keep or delete all subscriber data when uninstalling
the plugin.
