Integration
Schedule and publish to Tumblr
Every blog you can post to, group blogs included, is an account in SPREVA. Write the post, add tags, choose published or private, and let SPREVA publish on time.
What you can publish
Posts
Text, a link and up to 30 images.
Video posts
One video of up to 10 minutes, with a caption.
What SPREVA checks before it publishes
Every post is checked against these limits for each Tumblr account you picked, in the editor and again right before it goes out, so a problem shows up while you can still fix it.

How connecting works
You sign in with Tumblr and approve SPREVA. Every blog you can post to, including group blogs you belong to, becomes an account of its own, and you choose which ones this workspace uses.
Blogs are recognised by Tumblr's permanent id, so renaming a blog does not break publishing. Access renews on its own.
What SPREVA adds
Every blog, one post
Pick several blogs in the same post and give any of them its own text.
Tags
Add up to 30 tags per post, as many as Tumblr indexes on a new post.
Published or private
Publish to the blog, or post privately so only people who can already see the blog read it. Tumblr's own queue and drafts are not used, so what SPREVA reports as published really is on your blog.
Alt text from your library
The description saved on an image in Media goes out as its alt text on Tumblr.
And as on every network: its own text for any account, an approximate preview, publishing now, on a date or through a queue, a retry for only the accounts that failed, and each post's numbers read back into Analytics.
Questions about Tumblr
Can I schedule Tumblr posts?
Yes. Publish now, choose a date and time, or add the post to a queue in SPREVA, which publishes it straight to the blog when the time comes.
Can I post to several Tumblr blogs?
Yes. Each blog you can post to connects as an account of its own; pick as many as you like in one post.
How many tags can a Tumblr post have?
Up to 30, each up to 139 characters. Tags are separated by commas, so a tag cannot contain one.
Can I post a video to Tumblr?
Yes, as a video post: one video of up to 10 minutes, with your caption.
