Email tool that turns new blog posts into a newsletter automatically

Buttondown sounds like the closest fit: connect your blog’s RSS feed, and it can automatically email subscribers whenever you publish a new post. (docs.buttondown.com)

Other options:

• FeedBlitz — send each new post immediately, or bundle posts into weekly or monthly digests. (feedblitz.com)
• Mailchimp — supports scheduled RSS newsletters populated with new blog posts. (mailchimp.com)
• FeedToMail — a simple, blog-focused service that emails subscribers when a new post appears in your feed. (feedtomail.com)

If you share your blog platform and whether you want an email for every post or a weekly digest, I can narrow it down.

Several email platforms can publish new blog posts to subscribers automatically. The right one depends on whether you want a subscriber list (publisher) or just a personal inbox feed.

Email platforms with built-in RSS-to-email (for building a subscriber list)

• Mailchimp: You can automatically deliver fresh content to subscribers at intervals of your choosing, with options to send daily, weekly, or monthly. Mailchimp automates this with RSS campaigns.
• MailerLite: You enter the RSS feed URL, set the sending frequency, choose how many posts to include, and pick a design. It's a good fit if you want a simple setup.
• beehiiv: Its RSS-to-Send feature is set up under "Automations," where you enter your feed URL, customize the email format and scheduling, and enable the automation.
• Buttondown: It sends a new email each time you publish a blog post, podcast episode, or other content, and can also batch them on a weekly or monthly schedule.
• AWeber: Offers RSS-to-email setup where you connect your feed URL and set the newsletter schedule.
• Zoho Campaigns: You can create daily, weekly or monthly campaigns with a list of your latest blog updates.

Automation tools (flexible, for custom workflows)

• Zapier: Its "Digest by Zapier" action collects multiple RSS items and sends them as a single email at a set interval. One caveat: Zapier's free tier limits you to 100 tasks/month, which a single active news feed can exhaust in days.
• Make and IFTTT are alternatives in the same category, with IFTTT offering a simple single-step applet.

Personal digest tools (for your own inbox, not subscribers)

• Blogtrottr: Sends individual feed updates to your Gmail, free and instantly.
• Digest: New posts from your RSS feeds get delivered to your inbox as a digest.

How to choose

• If you want readers to sign up and receive your posts, pick a publisher platform like Mailchimp, MailerLite, Buttondown, or beehiiv.
• If you want a custom workflow connecting RSS to other apps, use Zapier or Make.
• If you only want updates for yourself, use Blogtrottr or Digest.

Prices change often, and some of the comparison pages I found are published by vendors with a stake in the results, so check current pricing and features on each provider's site before committing. If you tell me your blog platform, subscriber count, and budget, I can narrow this to one or two options.

Automating your blog-to-newsletter workflow is a highly effective way to stay consistent without the manual labor of drafting every email. There are several ways to achieve this, ranging from built-in platform features to advanced AI-driven workflows.

1. Built-in "RSS-to-Email" Features (Easiest)

Most modern Email Service Providers (ESPs) have a native feature that monitors your blog’s RSS feed and automatically triggers an email whenever a new post is published.

• MailerLite: Highly recommended for its ease of use. You can set up an RSS campaign that automatically pulls your latest posts into a pre-designed template.
• Beehiiv: Offers a native "RSS-to-Send" feature designed specifically for creators. It is well-integrated and handles the automation seamlessly.
• Buttondown: A minimalist, creator-focused tool that supports RSS automation as a paid add-on.
• Other Platforms: Many standard tools like Mailchimp and Constant Contact also have RSS-to-email functionality, though they are often more marketing/e-commerce focused.

2. AI-Powered Automation Tools (Best for Customization)

If you want your newsletter to do more than just send a "raw" feed—for example, if you want to summarize the post, change the tone, or curate multiple posts into one digest—use an AI-assisted automation tool.

• Hoppy Copy: Designed specifically to turn blog posts into newsletters. It connects to your blog, pulls highlights, and uses AI to rewrite them into a conversational, on-brand newsletter format before you send it.
• Taskade / Make / Zapier: These are "glue" tools. You can build a custom workflow that:
  1. Watches your RSS feed for new posts.
  2. Sends the content to an AI (like Claude or ChatGPT) to summarize it.
  3. Drafts the newsletter in your email platform (like MailerLite or Beehiiv) for your final review and click-to-send.
• RSS.app: An excellent utility that can turn almost any website into a clean, customizable RSS feed, which you can then plug into your chosen email platform to ensure the formatting looks perfect.

How to Choose

• If you want a "set it and forget it" system: Use the native RSS-to-Email feature in your current email platform (e.g., MailerLite or Beehiiv). It is free or low-cost and requires minimal maintenance.
• If you want a more editorial, "human" feel: Use Hoppy Copy. It bridges the gap between raw automation and a polished, written-by-a-human newsletter by letting AI handle the heavy lifting of summarizing and formatting.
• If you are a power user: Use Make or Zapier to create a custom pipeline. This allows you to combine multiple sources (e.g., your blog, industry news, social media) into one master weekly digest.

Recommendation: Start by checking if your current email provider has an "RSS-to-Email" or "Automated RSS Campaign" setting. If you find that the result looks too "automated" or "bot-like," look into Hoppy Copy to add that layer of AI-driven personality.

MailerLite is a good fit. Its RSS campaign feature turns new blog posts into newsletter emails automatically: add your blog’s RSS feed, choose a template and sending schedule, and set it to include only new posts. ¹⁵

Mailchimp also offers RSS-to-email automation, with daily, weekly, or monthly scheduling. ²³
