Whilst Twitter does allow third parties such as Sendible to post onto it, it is still a social networking site with the emphasis on users directly engaging with other users. Therefore, if your posts look too automated, they will be declined by this platform with the following message:
“This request looks like it might be automated. To protect our users from spam and other malicious activity, we can’t complete this action right now. Please try again later.”
To avoid your posts being declined for this reason, please try to vary the content and links included in posts to Twitter so that the same post or link is not posted consecutively.
