It depends a lot on what you're actually sending, so here's my take by use case — plus the handful of things that actually matter more than the platform choice.

If it's a newsletter / audience-building play

• •MailerLite — best value for bootstrapped. Solid automations, decent landing pages, free up to ~1,000 subscribers, and it stays cheap as you grow.
• •Kit (formerly ConvertKit) — better if you're selling courses/digital products to that list. Generous free tier, good tagging and sequence model.
• •Buttondown — if you want something dead simple, indie, and cheap. Markdown, great API, no bloat.
• •beehiiv — if growth and monetization are the point (referral program, recommendation network, built-in ad network).

If it's a SaaS and you need product/lifecycle email

• •Loops — purpose-built for this, clean, reasonable pricing for a solo founder.
• •Resend for transactional (password resets, receipts) — great DX, generous free tier. Pair with a marketing tool for campaigns.
• •Customer.io is more powerful but overkill and overpriced until you have real revenue.

If it's ecommerce

• •Klaviyo if you're on Shopify. Expensive, but the Shopify data integration genuinely pays for itself through abandoned-cart and post-purchase flows. Omnisend is the cheaper alternative.

I'd skip Mailchimp for anything new — pricing has gotten bad and the product hasn't kept pace.

The things that matter more than which tool you pick

• 1.Separate transactional from marketing sending. Use a different subdomain (mail.yourdomain.com for campaigns, notifications.yourdomain.com for transactional) at minimum. Otherwise one campaign that gets flagged as spam can take your password-reset emails down with it.

• 2.Set up SPF, DKIM, and DMARC properly from day one. Since Google and Yahoo tightened bulk-sender rules, this isn't optional. Most platforms walk you through it; actually do it rather than sending from their shared domain.

• 3.CAN-SPAM requires a valid physical mailing address in commercial emails. As a solo founder this usually means your home address, which most people don't want public. Get a virtual mailbox (Anytime Mailbox, iPostal1) or use your registered agent's address. Cheap problem to solve, annoying to discover after you've emailed 3,000 people.

• 4.Check how the platform counts contacts — some bill you for unsubscribed and bounced addresses, which quietly inflates your bill.

• 5.Verify export and API quality before committing. Migrating a list is painful, and you lose engagement history. Make sure you can leave.

One caveat: pricing and free tiers in this space change constantly, so confirm current numbers directly before you commit — my sense of the tiers may be out of date.

If you tell me what you're building and roughly who's on the list, I can narrow this to one recommendation.
