Question 32 · Sep 26 · Day 17

Claude on Question 32, Sep 26

I'm a solo bootstrapped founder in the US. What email marketing platform should I use?

It depends a lot on what you're actually sending, so here's my take by use case. Note that pricing in this space changes constantly, so verify current tiers before committing.

If you're building an audience / newsletter

  • •Kit (formerly ConvertKit) — my default recommendation for most solo founders. Free up to a fairly generous subscriber count, solid automation, good deliverability, and it handles paid subscriptions and digital product sales if you ever want that.
  • •MailerLite — cheapest credible option with a real automation builder. Slightly clunkier UI, excellent value.
  • •Buttondown — if you want something minimal and markdown-based. Indie-run, very cheap, popular with developers and writers.
  • •beehiiv — best growth/referral tooling and an ad network if you want to monetize a large list. Overkill under a few thousand subscribers.

I'd skip Mailchimp. It's gotten expensive relative to what you get, and the pricing scales badly.

If you're sending product/lifecycle emails from a SaaS app

  • •Loops — built for this, nice developer experience, reasonable flat pricing.
  • •Resend — if you want transactional and broadcasts in one place and you're comfortable in code. Cheap.
  • •Keep transactional (password resets, receipts) on a separate sending domain or subdomain from marketing. If your newsletter gets spam complaints, you don't want password resets going to junk.

If you're ecommerce

Klaviyo if you're on Shopify and revenue justifies it — the ROI on its flows is usually real. Omnisend if you want most of that for less.

Three things that matter more than the platform choice

  • 1.Send from your own domain and set up SPF, DKIM, and DMARC properly. Gmail and Yahoo now enforce this for bulk senders, and it's the single biggest lever on whether your email lands.
  • 2.Check the export path before you sign up. You want subscribers, tags, and ideally engagement history out in CSV with no friction. This is your main protection against price hikes.
  • 3.Watch how they price. Per-subscriber pricing punishes you for a big list you email rarely; per-send pricing (Brevo, for instance) punishes high frequency. Pick the model that matches your actual pattern.

What are you sending — broadcasts to a list you're growing, automated onboarding sequences for a product, or both? And roughly what list size are you at now? That'd let me narrow this down.
