It's high time you start growing your email list.

Don't cha' think?

Craft an enticing reader magnet that’ll earn you raving fans in our latest round of The Cookie Challenge: six weeks of story-baking goodness to get your reader magnet out the door!

Deep down, you know you need a reader magnet.

A good reader magnet turns casual buyers into superfans, and superfans into cheerleaders for your novels. It attracts more subscribers, lets you launch to a bigger audience, and is a key ingredient for success as an indie author.

But knowing and doing are two different things…


You don’t want to give away a novel for free—your work is worth paying for, damn it! But what else can you do?


Everyone says sample chapters aren’t exciting anymore. In a world of Kindle Unlimited, readers just don’t care.


Even if you get your cookie written (and those butterflies out of your stomach), how do deal with all the tech?


And wait a minute… Are you really saying I have to condense a full-length story into just 5,000 words!?

But this isn't something you can ignore.

If you’re serious about this whole indie-publishing thing, building an email audience (one you own, not Facebook or Amazon) is your first order of business.

Without readers in your orbit, you won’t have the support you need to launch new books, sell your backlist, or even get those precious early reviews.

That's where an enticing reader magnet really shines!

Having a high-quality reader magnet opens so many doors, from newsletter swaps to promo deals.

And even if you’re not ready to get deep into list-building just yet (no worries, you got time), this ensures the readers you do have land safe and sound on your newsletter, where you can stay in touch for the long term.

So let’s get this done, shall we?

Welcome to the Newsletter Ninja Cookie Challenge!

Here's what you'll achieve over

A well-written reader magnet is the #1 way to build your audience as an author. And if you’re savvy about it, you won’t need a new cookie for every book you write (unless that’s your jam, of course).


Though six weeks may seem like a lot, the work you do now will be welcoming new fans into your newsletter for years to come!

"Ok, But How Much Will This Cost Me?"

About half as much as a National Park Pass, that’s what. (Yes I had to Google it, but I’m committed to this bit)

Here's what past cookie-bakers have to say...

Hey there!
I'm Tammi. 🥷

And I translate all of that internet marketer… stuff… into strategies that work for authors.

For the better part of a decade, I’ve taught hundreds of students how to have fun with their email newsletters, while also running migrations for lists as small as 300 and as large as 150,000.

In the process, I’ve learned a thing or two about this whole list migration thing (often by finding what not to do—ha!).

List Migration Map is all of that wisdom packed into an approachable system you can use to migrate your email list with confidence, boost your deliverability, and build an engaged list of superfans.

If you’re an author looking to get serious about your email list, you’re in the right place!

Frequently Asked Questions

Yep! List Migration Map is service-agnostic, though I will recommend two email marketing services I think are particularly good fits for authors in the course. In terms of where you’re starting from though, you could be using Mailerlite, Convertkit, MailChimp, ActiveCampaign, Drip, Flodesk, Sendfox, or basically anything else. I’ll help you get organized and ready to move, no matter what EMS you’re using now.

Beyond List Migration Map itself, all you’ll need to invest in is a new email marketing service to actually move to. In the course, I’ll help you think about your budget and needs, and pick the right EMS for your situation, so you won’t have to figure that out on your own.

Every month, I run an open AMA/coaching call for all of my courses. During that call you can pick my brain (ew), ask questions, and get support as you whip your mailing list into shape. You might even end up rubbing shoulders with some students from my other courses, you socialite you!

Yes, technically, but I have very limited availability (you should see my poor calendar). If you want to chat about a custom list migration, you can get in touch here: https://newsletterninja.net/contact/

Send me a note through my contact page (https://newsletterninja.net/contact/) and my ninja-assistant Stacy will point you in the right direction.

Stuck on the fence?

Here's some tough love...

You can’t just dump your list into a new email marketing service and assume it’ll all go swimmingly.

Not only do your readers deserve a warmer welcome, but you (and your novels) deserve an engaged list that’s excited to hear from you. Shoving your subscribers into the back of a U-Haul and hoping they’ll survive the move is just a recipe for disaster.
