Native everywhere
Every version starts from your note and follows Tumblr’s rules in your voice. These are Refract’s defaults; turn any off, reword them or add your own in Voice and rules.
Tumblr rules to start with
Studio
Trim a clip, crop it for Tumblr, pick a cover and add captions. The original file never changes.
Timing
There’s no single best time to post on Tumblr for every account. The best time is when your own followers are around, and that depends on where they live and what they do all day.
Start with your audience’s time zone. If most of them live in one region, post in their morning, lunch break and evening, not yours.
Then post at the same times every week for a few weeks and compare. In Analytics, Top posts and each post’s numbers show which times worked: keep those and move the others.
In Refract, your posting times are set in Settings › Workspace, in the workspace’s time zone. Add to queue fills the next free one, the Calendar shows the open slots, and Repeat keeps a regular post on schedule.
Checks
Checks run while you write, with a fix for each one. They come from the same rules the server uses, so a post that passes here won’t be rejected later.
