Below are the writing tools, books, and reference tools that I use and can recommend. Some of the links have affiliate codes at the end, but this does not affect my recommendation in any way. I would have recommended it, even if there was no affiliate program.
Distribution Of eBooks
Formatting & Publishing of eBooks
Draft2Digital – an aggregator that will send your manuscripts to various eBook platforms. They now offer templates for formatting your books, which are free to use and can be exported to other platforms.
PublishDrive – another aggregator but this one distributes your books to different international markets.
It also gets the book onto Google Play, which is normally quite difficult to do (UPDATE : I now don’t recommend you put your book on Google Play. I recently found large chunks of my book on Google Books, reproduced without my permission).
Vellum – VERY pricey but very worth it. This should be seen as a long-term investment that will reap dividends in the long run.
Marketing & Promotion
Mailchimp – excellent mailing list service, although it rapidly gets very pricey as your list expands. I am considering switching to Mailerlite.
Buffer – used to automate social media updates on Twitter and Facebook.
StatusBrew – used to automate free book download links to new prospects on Twitter.
Ratings Catcher – sends you an email when you get new reviews for your books (I’ve stopped using this now, due to the cost, but a free option which works quite well is Deep Watch).
Google Office : I personally use Google Docs to write my manuscripts and Google Sheets to keep track of sales and downloads.
Book Report : The Amazon KDP dashboard can be confusing to analyse with all of the different currencies. If you want a real-time updating of your current earnings, as well as being told what your bestselling books are, “Book Report” is absolutely essential. It is a free bookmark tool (until you reach a certain income amount) which lies on top of your normal KDP screen. Amazon should be buying this and giving it to their customers by default.
