Automate Mailchimp to WordPress
If you’re tired of copying and pasting every email campaign from Mailchimp into WordPress, this automation will change your workflow forever. In this post, I’ll show you how to connect Mailchimp and WordPress using OttoKit so that every time you send a campaign, it instantly becomes a formatted blog post—no manual work required. This setup will save you hours, keep your content consistent, and help you stay focused on the creative work that really grows your business.
Why Automate Mailchimp to WordPress?
As a small business owner or coach, your time is precious. Automating your processes means fewer repetitive tasks and fewer chances to forget something important. With this Mailchimp-to-WordPress automation, you’ll:
- Save time by skipping manual content uploads
- Eliminate formatting issues caused by messy email HTML
- Keep your blog fresh with every newsletter automatically published
- Organize your campaigns by topic or membership tier
Step 1: Create a Webhook Trigger in OttoKit
The automation starts in OttoKit, a no-code tool that connects your favorite apps. Begin by creating a new workflow and selecting Webhooks as your trigger. You’ll want to listen for a simple event: when an email campaign is sent in Mailchimp.
OttoKit will generate a webhook URL. Copy that URL—we’ll need it in the next step.
Step 2: Configure the Webhook in Mailchimp
Now, inside your Mailchimp account, go to Audience Settings → Webhooks → Create Webhook. Paste the OttoKit webhook URL into the callback field. For the events, select Campaign Sending, and under “Source,” choose via the API. Then click Create Webhook.
Back inOttoKit, send yourself a quick test campaign to ensure everything is working. Once Mailchimp sends the email, you’ll see the webhook fire in OttoKit—success!
Step 3: Fetch the Campaign Content
The webhook tells OttoKit that something was sent, but it doesn’t include the full content. The next action step is to fetch the campaign data from Mailchimp via API. You’ll need to create an API connection between Mailchimp and OttoKit (super easy—just generate a Mailchimp API key and paste it into OttoKit).
From the fetched data, you’ll grab the archive URL, which contains the full version of your email. You’ll need this for the next step.
Step 4: Clean Up Email HTML with Jina AI
Email HTML can be messy—full of tables, inline styles, and tracking code. That’s not what we want on a clean WordPress blog. I use Jina AI to convert the raw email into structured, readable HTML. In OttoKit, create an API Request step and connect it to Gina’s endpoint, using a POST method.
In your configuration, send the long archive URL from Mailchimp as input. Gina AI will extract just the body content—no headers, footers, or tracking—and return it as clean, web-ready HTML.
Step 5: Reformat for WordPress Using ChatGPT
Now that we’ve got usable HTML, I run it through ChatGPT (using the latest model) to make it blog-ready. I tell ChatGPT to act as an “expert WordPress content editor” and convert the cleaned HTML into well-structured, semantic HTML optimized for WordPress.
This step polishes the layout, structures headings properly, and ensures that the post looks professional once published on your site.
Step 6: Publish to WordPress Automatically
Finally, the last step pushes the content directly to WordPress. Install the OttoKit plugin on your WordPress website and create the connection.
Under configuration:
- Set the post type to Post (you can choose Draft, Published, or Scheduled)
- Use the campaign’s subject line as the post title
- Map your categories and author info
- Insert the cleaned HTML from ChatGPT as the post content
If you want to get fancy, you can even use conditional filters—for example, only publish posts if the campaign name includes “Members” or “Newsletter.” That’s perfect for segmenting public vs. premium content.
Optional: Add a Featured Image or Enhance SEO
Before the WordPress action step, you could add another call to an AI service (like Gemini) to generate a featured image or SEO-friendly metadata. It’s optional, but a nice touch for making posts more visually appealing and searchable.
Enjoy Hands-Off Blogging
From now on, whenever I hit “Send” on a Mailchimp campaign, OttoKit automatically converts and publishes it as a sleek WordPress post. No more copy-paste. No more broken formatting. Just seamless content distribution across two powerful platforms.
