RSVPMaker is an event and email marketing tool. Use PayPal or Stripe to collect event payments. RSVPMaker handles scheduling, event marketing, and RSVP tracking. You can send email to small lists through your web server or take advantage of the integrations with Postmark and Mailchimp to scale up. When implemented in combination with Postmark for reliable email delivery, RSVPMaker can function as an alternative to Mailchimp or MailPoet that allows you to format messages in the WordPress editor and easily incorporate events (for invitations) and blog posts or excerpts from posts (for email newsletters and promotions). Use RSVPMaker to: – Schedule and promote events of all sorts: conferences, classes, seminars, speaking events, parties and weddings are a few common uses. – Register attendees, prompting them to enter whatever information you need, including the names of guests. – Collect money using PayPal or Stripe. – Create webinars and other online events leveraging free resources like the YouTube Live service. – Create, format, and edit email newsletters within the WordPress block editor, rather than learning another content composer tool. Use dynamic blocks or shortcodes to incorporate dynamic content like lists of recent blog posts or upcoming events. – Power membership-oriented websites with tools for emailing all your members or just those who have or have not registered for a specific event. – Send email using your own web server, an SMTP plugin or the integrations with Mailchimp and Postmark. – Postmark integration has the advantage of supporting both broadcast / mailing list and transactional messages (like RSVP Confirmations). Creating and Managing Events RSVPMaker events are created and edited just like blog posts in the WordPress editor, with the addition of parameters like event date (so the items can be listed chronologically and displayed on a calendar grid). Explore the editing experience with this WordPress Playground demo (created using the author’s Quick Playground plugin) You can use RSVPMaker for event announcements, or turn on the Collect RSVPs function and set additional options for sending email notifications, customizing confirmation and reminder messages, and setting a price or prices if you will be requesting online payments via PayPal. RSVP reports can be viewed on the administrator’s dashboard or downloaded as spreadsheets. If you hold events on a recurring schedule, such as First Monday or Every Friday, you can define a template with the boilerplate details and quickly generate multiple entries that follow that schedule. Individual event posts can still be customized. For example, you might book a series of monthly events for the year and add the names of speakers or agenda details as you go along. The RSVP Mailer tool allows you to use the familiar WordPress editor to format email newsletters and promotional messages, which can include embedded events and other dynamic content from your website. You use the same tools to format transactional messages such as confirmation and reminder messages. Hosting and Support RSVPMaker is a free plugin that doesn’t hold much back in terms of “premium” features. The plugin author is available to consult on customizations, but most generally useful enhancements are folded back into the core plugin code. RSVPMaker also aims to be developer-friendly, allowing you to build event-centric applications on top of it. Hosting and support of pre-configured websites is available through RSVPMaker.com. RSVPMaker.com uses Siteground hosting behind the scenes and Postmark for reliable delivery of email newsletters and transactional messages.
