I came across this article on Twitter (follow me @OrangeJulius7) last month from Writer’s Relief:
“Online Writing Submissions: Mistakes Writers Make Submitting to Literary Agents and Editors”
Here’s a few tips I learned:
- Don’t rush. Take your time, follow ALL of the guidelines.
- Don’t forget to actually SUBMIT the work.
- Proofread (no typos or slang).
What are you experiences with online submissions? Any tips for sending a query letter through email?
