Question 32 · Sep 26 · Day 17

GPT on Question 32, Sep 26

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

For most solo bootstrapped founders, I’d start with MailerLite.

Best default: MailerLite

Why: affordable, easy to operate alone, solid automations, landing pages, forms, and enough segmentation for an early-stage SaaS, service, or ecommerce-adjacent business. It generally offers a better simplicity-to-capability ratio than heavier tools.

Choose something else if…

Audience/newsletter is the businessKitStrong creator automations, tagging, lead magnets, and digital-product workflows

Ecommerce, especially ShopifyKlaviyoPowerful revenue attribution and behavioral automations, but expensive
Complex B2B CRM and sales workflowsHubSpotBroad CRM ecosystem, but cost and complexity escalate quickly
Maximum flexibility and low sending costAmazon SES + a front endCheap at scale, but requires more technical setup and maintenance

My practical recommendation

  • •Early-stage SaaS or service business: MailerLite
  • •Creator selling courses, memberships, or downloads: Kit
  • •Media-style newsletter: beehiiv
  • •Shopify store: Klaviyo
  • •Need product emails too: use MailerLite for marketing and a dedicated transactional provider such as Postmark, Resend, or Amazon SES

Avoid choosing based only on the free tier. Compare the price at your expected subscriber count in 12 months, and check whether automation, additional users, and transactional email cost extra.

Whichever platform you choose, authenticate your domain with SPF, DKIM, and DMARC, use confirmed opt-in where appropriate, include a physical mailing address and unsubscribe link, and don’t send marketing email to purchased lists. Pricing and plan limits change often, so verify current terms before committing.
