  • Hi @bspabla,

    I apologize for the trouble but Gmail isn’t designed for sending bulk email. While you can send emails to a maximum of 500 recipients per day, the limit for the recipients per message seems to be 100. Please do NOT take this information for granted, Gmail can change its email policy without any prior notification.

    An alternative is to use one of the other mailer options within WP Mail SMTP such as Mailgun and Sendgrid.

    Thank You!
