Pressidium provides SMTP integration via MailChannels for regular website email. You do not need an SMTP plugin for ordinary WordPress mail, and there is no customer-facing SMTP host, port, or username for that relay.

The platform is not designed for mass mailing. For newsletters, campaigns, or bulk sending, use a third-party service such as SendGrid, Mailchimp, or GetResponse.

MailChannels may apply its own sending limits. This page does not list a numeric cap. If you need the limit that applies to your account, open a Support request and include the website.

For when a third-party SMTP plugin is appropriate, and for the MailChannels SPF TXT guide, see Email limits.

If you need a numeric sending limit for your account, or legitimate site mail is not arriving, open a Support request. Include the website and whether you are sending ordinary WordPress mail or a bulk campaign.
