How to schedule Tumblr Posts
- Sign in with Tumblr. On the calendar page choose Add Channel, then Tumblr. Sign in with Tumblr and approve the permissions PostDelegate asks for: posting to your blogs and staying signed in.
- Choose the blog. Choose the blog to connect. To post to another blog on the same account, add it as a second channel.
- Write the post. Choose Create Post and select the Tumblr channel. Write the text, up to 32,768 characters, and add up to 30 images or one MP4 video.
- Add settings and schedule. Optionally add a title, link URL, source URL and tags separated by commas. Pick a date and time and choose Add to Calendar.
What you can publish to Tumblr
Tumblr is a blogging platform, and a PostDelegate post becomes one post on the blog you connected. It can hold long text, up to 30 images or a single MP4 video, with an optional title, a link, a source credit and tags.
You connect through Tumblr's own sign-in, so PostDelegate never sees your Tumblr password. If your account has several blogs, connect each one as its own channel and pick the right one in the composer.
- Sign in with Tumblr and choose the blog to connect.
- Write text and add up to 30 images or one MP4 video.
- Add an optional title, link, source credit and tags.
Tumblr post settings
| Setting | Notes |
|---|---|
| Title | Optional. Shown as a heading at the top of the post. |
| Link URL | Optional. Added to the post as a link. |
| Source URL | Optional. Credits where the content came from. |
| Tags | Optional. Separate tags with commas. |
Before connecting
- Each post is published straight away on the blog, not saved as a draft on Tumblr. Keep a draft in PostDelegate to hold it back.
- Tumblr caps how many posts, uploads and videos a blog can publish each day. A post over the cap fails with Tumblr's reason.
Read the Tumblr guide in our documentation for connection steps, post settings and troubleshooting.
Plan Tumblr with the rest of your channels
Tumblr sits on the same calendar as every other channel you connect. In one post you can pick several channels, write the content once and adjust it for each, and every channel keeps its own settings. Save a draft to review a post first, choose Add to Calendar to schedule it, or choose Post now to send it immediately. The scheduling guide covers drafts, repeats, previews and time slots.
Use Claude or ChatGPT with Tumblr
PostDelegate runs an MCP server, so an assistant you already use can look at your Tumblr channel, read its rules and create a draft for you to review. AI is bring-your-own, and PostDelegate never charges for it. Setup guides: Claude, ChatGPT, and what a social media MCP server is.
Review the whole post
Check the destination, wording, media and time before scheduling. Look at the result in your workspace after publication; a queued item is not a published-post confirmation.
