GPT on Question 32, Oct 3

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

Best default for a solo bootstrapped founder: MailerLite.

It’s relatively inexpensive, easy to operate, and includes the essentials—newsletters, forms, landing pages, segmentation, and basic automations—without the complexity of enterprise tools.

Choose something else if your business fits one of these cases:

  • •Creator, coach, or digital products: Kit — strong tagging, sequences, and creator-focused integrations.
  • •Newsletter publication/media business: beehiiv — better publishing, referral, and monetization features.
  • •Shopify/e-commerce: Klaviyo — powerful revenue attribution and store automations, though more expensive.
  • •SaaS product/lifecycle emails: Loops — simple, developer-friendly customer messaging. Consider Customer.io only once your needs become complex.
  • •High sending volume, transactional email, or SMS: Brevo — often cost-effective when send volume matters more than contact count.
  • •CRM-first sales process: HubSpot — useful if you genuinely need its CRM ecosystem; otherwise likely overkill.

I’d generally avoid starting with Mailchimp unless a required integration makes it the obvious choice; pricing and automation complexity can become frustrating as your list grows.

Practical setup

  • 1.Start with MailerLite.
  • 2.Authenticate your domain with SPF, DKIM, and DMARC.
  • 3.Use a branded sending address—not Gmail.
  • 4.Create one welcome sequence and one regular newsletter before building elaborate automations.
  • 5.Include an unsubscribe link and physical mailing address to comply with CAN-SPAM.
  • 6.Don’t use a marketing platform for purchased lists or mass cold outreach.

Short answer: MailerLite for most bootstrapped founders; Kit for creator businesses; Klaviyo for e-commerce; Loops for SaaS.
