Should You Delete Your Tumblr Account? When you accept the deletion request, your likes, messages, and primary blog material will be permanently deleted from the site.
When you delete your Tumblr blog or account, everything stored on it is destroyed. This does not, however, apply to any material that other people have reblogged from you.
Your blogs, messages, and all activities are permanently deleted when you delete your Tumblr account. You won’t be able to login into your account, find your blog using your URL, or read through your correspondence.
If you don’t log in to your Tumblr account within a year, the site will send you an email to reclaim it. If you take no action, your username will expire. In March 2016, Tumblr began freeing up usernames on accounts with no login activity for two years and switched to one year of inactivity.
It’s possible that your Tumblr account is no longer available. It’s either totally or permanently deleted after you delete it. There’s no way to bring back your old one. The only alternative is to start a new blog. If the information is still accessible, you may look in the digital library for a brief history of your blog.
