Email Marketing
Email is still the channel a solo founder actually owns — no algorithm decides who sees it. The trap is picking a platform built for a marketing team's approval workflow instead of one person who needs to write, design, and send a campaign in under an hour. These five are the platforms solo founders ask about most, shortlisted for how they behave at a few hundred to a few thousand subscribers, not at enterprise scale.
1. ConvertKit
Best overall for creatorsBest for: newsletter-first businesses and course creators
ConvertKit (now Kit) was built around creators rather than ecommerce brands, and it shows: tagging and automations are built for a solo writer segmenting a list, not a marketing department managing approval chains.
Strengths
- Visual automation builder that stays readable at 10+ branching steps
- Free plan up to 10,000 subscribers with core automation features included
- Landing pages and forms built in, so you can capture emails without a separate tool
Watch out for
- Email designer is plainer than Mailchimp's — fine for text-first newsletters, less so for image-heavy campaigns
- Reporting is thinner than ActiveCampaign's if you want deep attribution
2. Mailchimp
Best for ecommerce add-onsBest for: stores and brands that want marketing + light CRM in one tool
Mailchimp is the household name for a reason — broad integrations, a mature template library, and ecommerce-specific automations (abandoned cart, product recommendations) that are hard to match at this price.
Strengths
- Deep ecommerce integrations (Shopify, WooCommerce) with pre-built automations
- Large template and design library for polished, image-heavy sends
- Free tier exists, though it's the most limited of this group
Watch out for
- Pricing climbs quickly once you pass a few thousand contacts, and it counts unsubscribed contacts on some legacy plans
- Automation builder feels more rigid than ConvertKit's once flows get complex
3. Brevo
Best price-per-subscriberBest for: founders who also want SMS and a shared inbox in the same tool
Brevo (formerly Sendinblue) prices by emails sent per month rather than list size, which rewards a small, engaged list — plus it bundles SMS, a CRM, and live chat, which can replace a couple of separate tools.
Strengths
- Send-based pricing means a large list with low send frequency stays cheap
- SMS marketing and a basic CRM included without another subscription
- Solid deliverability reputation and transactional email support
Watch out for
- Automation builder isn't as visually intuitive as ConvertKit's or ActiveCampaign's
- Free plan caps daily sends fairly low, which forces an upgrade sooner than list size alone would suggest
4. MailerLite
Best for tight budgetsBest for: early-stage founders who want automation without a steep learning curve
MailerLite undercuts most of this list on price while still offering a real automation builder, making it the pick for someone validating an idea before committing to a pricier platform.
Strengths
- Generous free plan (up to 1,000 subscribers) with automations included, not gated to paid tiers
- Clean, fast editor with a genuinely gentle learning curve
- Built-in landing pages and a simple website builder for a one-page launch
Watch out for
- Advanced segmentation and reporting lag behind ActiveCampaign and Brevo
- Third-party integrations are a shorter list than the bigger platforms
5. ActiveCampaign
Best automation depthBest for: founders who want CRM-grade automation and lead scoring
ActiveCampaign is the most powerful automation engine here — conditional branching, lead scoring, and a built-in CRM — but that power comes with a steeper setup curve and a higher price floor.
Strengths
- Automation builder handles genuinely complex, multi-branch logic without breaking down
- Built-in CRM/pipeline view useful if email marketing overlaps with sales outreach
- Strong deliverability tooling and send-time optimization
Watch out for
- No meaningful free plan, and pricing rises fast per contact past the entry tier
- Overkill and slower to learn if you just need a simple monthly newsletter
Questions solo founders ask about email marketing
Do I need email marketing software if I already use a CRM?
If your CRM sends polished, trackable newsletters with automation and deliverability monitoring built in, you may not need a separate tool. In practice, most CRMs treat email as a secondary feature, so a dedicated platform usually sends better and gives clearer open/click data.
What actually changes pricing as my list grows?
Most of these tools price on either the number of contacts stored or the number of emails sent per month. Brevo's send-based pricing rewards a large but rarely-emailed list; the rest scale with subscriber count, so pruning inactive subscribers directly saves money.
Can I switch platforms later without losing my list?
Yes — every tool on this list supports CSV export of contacts, tags, and (on most) automation logic in some form. The real switching cost is usually rebuilding automations and templates by hand, not the data itself.
