Configure your preferred mail delivery method depending on your current setup and availability options in Jetpack CRM.
WordPress is a versatile platform and can handle small-scale email sending well. However, emails sent from a WordPress site often face deliverability challenges because their success depends heavily on your web server’s reputation.
For example, if you’re on shared hosting and another user on your server sends spam, your emails may get blocked or marked as spam, even if you haven’t sent any spam yourselves.
To address these challenges, you can send emails in Jetpack CRM through trusted third-party email servers, by configuring your preferred mail delivery method – instead of relying solely on your web host.
Mail delivery manager in Jetpack CRM
To give you full control over outbound email reliability and appearance, Jetpack CRM provides the following:
- Mail templating: customize your system emails’ content and layout.
- Mail delivery options: configure one or more email accounts to send your system emails from, using professional-grade email technology.
Currently, Jetpack CRM supports three mail delivery methods:
- Default WordPress mail (wp_mail): sends emails via your WordPress server. You can update the “from” name and email address, but typically the email domain must match your site domain to ensure deliverability.
- OAuth API-based connection: ideal for Gmail or Google Workspace users to securely send emails using Google’s API.
- SMTP (Outgoing Mail Server): use your existing email provider’s SMTP server (e.g., Outlook, Zoho), or specialized services like Amazon SES for high-volume sending with excellent deliverability.
Sett up Mail Delivery Options
To configure mail delivery, follow these simple steps:
- Navigate to Jetpack CRM → CRM Settings.
- Open the Mail Delivery Wizard, then scroll down to the Mail Delivery section and click it.

Email sending limitations
Your hourly email sending limit largely depends on your configured mail delivery setup. For example, with wp_mail or Gmail, sending more than 600 emails per hour can trigger spam filters.
For most users, wp-cron is sufficient for scheduled email sending, but it has limitations. For high-frequency or large campaigns, using server-cron is recommended for better reliability.
