SoMePoster can publish messages straight to your Discord server through a connected webhook. Here's how to post to Discord once your server is connected.
Go to Create Post and Select Discord
Go to Create Post and select Discord at the top of the page.
Select the Channels
Each connected webhook is one channel, and you can pick several.
Write Your Post
Write your post — text, links, and emoji all work. Optionally add images (up to 10 are uploaded with the message), or turn on Edit Content/Image Per Platform if you're posting elsewhere too.
Publish
Choose Post Now or Schedule, then Publish.
Check the Result in My Posts
Go to My Posts to see the status — Published, Processing, Failed, or Scheduled.
About the Post Link
The post link opens the message in Discord, but only for members of that server. Discord has no public web page for a message, so it won't open for anyone else, and search engines can't read it.
