Claude on Question 32, Sep 15

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

It depends a lot on what the emails are for — that's the fork in the road. Here's how I'd think about it, with a pick for each common case:

If you're writing a newsletter / audience-first content play
Go with beehiiv or Ghost. beehiiv has a generous free tier (a couple thousand subscribers), built-in referral program, recommendation network, and an ad marketplace if you ever want sponsor revenue. Ghost is better if you want the newsletter and the website/blog in one place and dislike revenue cuts — it only charges hosting, not a percentage of paid subscriptions. Avoid Substack unless distribution-via-Substack-network is the whole point; you're renting your brand and paying 10% of revenue forever.

If you're building a SaaS or app and need both product emails and marketing emails
Loops is the one I'd try first. It's built for exactly this — one tool for transactional (password resets, receipts) and lifecycle/marketing (onboarding sequences, feature announcements), clean API, sane pricing for small volume. Resend is the alternative if you're comfortable in code and want the transactional layer to be rock-solid, with lighter marketing features on top. Customer.io is the "grown-up" version of this but overkill and overpriced until you have real revenue.

If you're selling physical products / running a store
Klaviyo if you're on Shopify and expect email to be a real revenue channel — it's expensive but the ecommerce integrations and pre-built flows genuinely pay for themselves. Omnisend if you want most of that for less.

If you just need something cheap and general-purpose right now
MailerLite. Free to 1,000 subscribers, solid automations, decent landing pages and forms, and the paid tiers stay cheap as you grow. It's the boring correct answer for a bootstrapper who doesn't yet know what they need.

What I'd steer you away from: Mailchimp (pricing got hostile, and it bills you for unsubscribed contacts) and HubSpot (priced for funded teams).

A few things that matter more than the logo you pick:

•Authenticate your own sending domain (SPF, DKIM, DMARC) on day one. Do it on a subdomain like mail.yourdomain.com so a deliverability problem doesn't poison your main domain. This also makes migrating later much less painful.
•Separate transactional from marketing sending, ideally different subdomains. You don't want a promo blast tanking the deliverability of your password-reset emails.
•Check that export is easy before you commit — subscribers, tags, and ideally engagement history. Switching platforms is a normal thing to do once or twice.
•US means CAN-SPAM, which is light: accurate from/subject lines, a physical mailing address in the footer (a virtual mailbox or registered agent address is fine), and working one-click unsubscribe honored promptly. If you'll have any EU/UK subscribers, run consent-based opt-in from the start — retrofitting consent is miserable.

If you tell me what you're actually shipping and roughly how technical you are, I can narrow it to one.
