Question 32 · Sep 21 · Day 12

Claude on Question 32, Sep 21

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

It depends a lot on which job you're hiring it for, since "email marketing" covers three pretty different needs. Here's how I'd break it down:

If you're building an audience / newsletter

  • •Buttondown — indie-built, cheap, clean, great if you like Markdown and simplicity. Very popular with technical solo founders.
  • •Kit (formerly ConvertKit) — stronger on landing pages, forms, and automation sequences. Generous free tier to start.
  • •beehiiv — best if growth/referrals/ad monetization matter to you.

If you're sending product emails from a SaaS (onboarding, lifecycle, trial nudges)

  • •Loops — built for exactly this, very popular in the indie SaaS world, nice balance of dev API + marketing UI.
  • •Resend — developer-first, cheap, handles both transactional and broadcasts. Good if you're comfortable in code.
  • •Postmark — if deliverability on critical transactional email (password resets, receipts) is the priority. Often paired with a separate marketing tool.

If you're doing ecommerce

  • •Klaviyo is the default, though it gets expensive as your list grows. Omnisend or MailerLite are cheaper alternatives.

General advice regardless of pick:

  • •Skip Mailchimp. It's expensive relative to alternatives and has historically billed on total contacts including unsubscribes.
  • •Send from your own domain and set up SPF, DKIM, and DMARC on day one. This matters more for deliverability than which platform you choose.
  • •Check export before you commit. You want your list and ideally your email content out in a usable format if you leave.
  • •Don't overbuy. Advanced segmentation and multi-branch automations are worth nothing at 200 subscribers. Start cheap, migrate when a real constraint bites.
  • •CAN-SPAM requires a working unsubscribe and a physical mailing address in commercial emails — a PO box or virtual address is fine if you don't want your home address out there.

What are you actually sending — newsletter content, product lifecycle emails, or both? And roughly what list size? That'd let me narrow this to one or two.
