If you were me, how would you grow this newsletter to 2500 subscribers? Currently have 95.

Who is this newsletter for? How will this help them? Answering those questions in the Landing Page copy would help. What do the first 95 have in common?

i would recommend that you start looking for people who might share some of your thoughts and opinion or some who want to have an other perspective about certain subject. to be honest i would not subscribe to the newsletter because the description say nothing about what is it or some thing you previously shared.
i think maybe some example can do the job.
also be specifique about the things you will share. you say "i make suggestions on what to read" maybe if you could specify the domains that you will suggest on might help get better targeting.
also take a look in Quora, Reddit, Telegram groups that match the topics you want to share and talk about.

this what 's come to my mind now. i hope it help

Cool, Inspired me by your post since I was after a plan that I was building for one of my package.

A feedback to you would be make it targeted and include more posts based on facts or data. People love research, studies & future projection reports in the niche that you talk about and I would say the success of every newsletter lies on it when somebody endorse the newsletter to others.

Can you do something like the "best of" series? Maybe a landing page that curates the best of what you've read/listened to, spent money on, thought about - each represents a different angle. i.e. Carrot Cake Read, Carrot Cake Listen, Carrot Cake Money, etc... - I'm curious which "vertical" gets you the most subscriber growth and which one is easily sharable and snackable. Perhaps once you know which one is the most viral driver, you can double down on some cool contents/rewards around that.
How are your 95 subscribers becoming your biggest fans? Are there natural ways for them to share to their network? Have you tried incentivizing the virality? I know Morning Brew had a really good program that would basically gamify users sharing. For every milestone of sharing (i.e. 5 sign ups, 15 sign ups, 30 sign ups) they would give that user a Morning Brew mug or something similar.

That is an ambitious goal!

It took me 14 months to grow my newsletter Creativerly to 100 subscribers. I did not take any specific marketing measures. I just bought a domain, set up a quick landing page using Carrd, secured the Twitter and Instagram handles and started to post my content.

Whenever I send out a new newsletter issue I shared it on my Twitter Accounts, and also sometimes to LinkedIn.

What really worked out well in first place was to be active in to my newsletter related communities. I write about the fields of design and tech, so I tried to be really active on different subreddits and comment on people's posts. But I did not just plug my newsletter, I tried to provide real value with my comment and after that writing something like "I share more of this in my weekly newsletter, you can check it out here, if you like it let me know". That worked out well in building up an audience.

I also just posted a Milestone here on Indie Hackers. Keep your community informed and updated. Constantly writing and posting about my progress with my newsletter also gained me some new followers, and you get a lot of great feedback, which might, might not help you, but you keep engaging with potential subscribers.

So keep sharing your newsletter, on social media, in communities, etc. when people start sharing your newsletter, word of mouth will also kick in and you will gain new subscribers. What I have also learned: Keep sharing the very best content. People tend to let things go once they reached a decent amount of followers/subscribers since they think they just share something they came across. But your subscribers are subscribing to your newsletter because they want one thing: the best content, curated by you because they trust you and your expertise and that specific field to filter good, great and the best content.

Have you seen https://email1k.com/ ? It's a 30 day free course, perhaps it can help you.

Funnily, it's more interesting to analyze the way they try to pitch to you during the course, than paying attention to the content itself.

I feel what to read, what to listen to, spend money on is different for different kinds of customers.

I would clearly define who is my ideal customer, what would they like to read, where do they hang out. Becomes easier when you focus

As some has already suggested. Pick a niche. Something your subscribers will have in common and potential subscribers can relate to. Since you are posting on Indie Hackers, my guess is that you are into that. Maybe "What to read, watch, listen to, and think about as an aspiring Indie Hacker"...? You get my point :)

I would:

1. Buy a domain. I'm more likely to subscribe to carrotcake.email or something sweet like that. Landing page design can be very simple.
2. Move this thing over to MailChimp. I think their templates will allow you to customize the email design a bit more. They have free domains now too https://mailchimp.com/features/domains/
3. Get a logo. 🥕 I actually really like the name so don't change that.
4. Hyperlink out to all the stuff you are featuring.
5. Sign off with your twitter handle or asking to "reply to this email". Some of these just sort of end.
6. Copy Ben Evans use of emoji for headers https://us6.campaign-archive.com/?u=b98e2de85f03865f1d38de74f&id=4f2ee03193
7. Start tweeting out a link to each issue when it goes out.

1. Did you find these 95 folks in any specific 'places'? If so, target more over there. If not, figure out a pattern (if it exists) across these subscribers and try to repeat it

2. As a newbie to 'your world', I tried signing up - But I had no idea what (and why) I would sign up for given the above linked landing page. Having samples of your previous email newsletters may help!
