The number of automations depends on the tier. - **Send your latest posts:** Send new posts, products, events or other custom post types, and use them to trigger automations. - **Editor and templates:** A drag-and-drop editor with more than 400 free and premium templates. - **Any sending provider:** Mail can go out through SMTP or an email service provider; integrations are available for services such as Mailgun, SendGrid, SparkPost, Mailjet and Gmail. - **Segmentation and tracking:** Segment subscribers and track opens, clicks, email providers and locations from within WordPress. - **Precheck:** A pre-send check that flags issues in a campaign, capped at 10, 100 or 1,000 runs a month by tier. ## Good for - WordPress site owners who want subscriber data to stay in their own database - Publishers who want new posts emailed automatically - Anyone who prefers a yearly licence over pricing by list size ## Worth knowing - It runs only inside WordPress, and every licence covers one site or domain. - There is no free edition; the site offers a demo and a 14-day money-back guarantee. - Updates and support need an active licence. The plugin keeps working after expiry, but renewals are at full price. - Mailster does not send mail itself. Deliverability depends on the email provider or server you connect, and the vendor recommends a dedicated provider. ## ToolGPA grades **GPA: 1.8 out of 4**, graded Nov 13, 2026. Mailster is a WordPress plugin that sends newsletters from your own site, with unlimited subscribers on every tier. It costs $79 a year for one site, but you still need a separate sending service, only 3 automations come on the entry tier, and it's no use if you're not on WordPress. - **Value for money: B.** $79 a year for 1 site is about $6.60 a month, inside the cheaper quarter of email tools ($9.99). The first-year price is $39, then it renews at full price, and you pay your sending provider on top. - **Free plan and trial: F.** No free edition and no trial. There's a demo and a 14-day money-back guarantee, which isn't the same thing. - **Features: C.** Newsletters, drip emails, post-triggered sends, a template editor and segmentation. But Starter has 3 automations, and it doesn't send mail itself, so delivery depends on the provider you connect. - **Ease of use: D.** You need a WordPress site that you host and keep updated, plus an SMTP or email-service connection. No rating on record. - **Platforms and integrations: B.** Web only, inside WordPress, but it connects to Mailgun, SendGrid, SparkPost, Mailjet, Gmail and Gravity Forms, among others.

The category's chart of price against score: https://toolgpa.com/charts/email-marketing ## Keep it, or make your own? **Keep it.** To replace Mailster you would be making newsletters sent to thousands of people that still reach the inbox. That is not a weekend's work, with an AI app builder or without one. That makes this kind of software worth paying for, not this one in particular: 51 of the 57 other email marketing and newsletter tools grade higher. It costs $79 a year. - You could make: Templates, forms and rSS reader: an app builder makes these well. - You could not: Newsletters sent to thousands of people that still reach the inbox. - You could not: Email sent in volume that still reaches the inbox. - You could not: It plugs into other products, Mailgun, SendGrid and SparkPost among them.
