Signal is an amazing tool that makes automating tweets of your blog posts a breeze! It is one of my most frequently recommended blogging tools!
Best of all, you can try Signal for free! The free plan is limited to three tweets, but this should be enough for you to determine how useful the tool is. If you want to upgrade to the premium plan, it will cost you $6.99 per month. However, this allows you to create an unlimited number of automatically posted tweets, which is well worth the money if you want to promote your articles at scale.
