1. AWeber — Most Reliable for B2B Email
AWeber has been running since 1998. That is not a knock — it means 25 years of optimizing email deliverability. For B2B content where you are writing to founders and decision-makers at corporate email addresses, inbox placement is everything.
The free plan covers 500 subscribers with unlimited sends, automation, landing pages, and 700+ email templates. No time limit. Full features.
If you are building a B2B content newsletter and your primary goal is getting emails into primary inboxes (not promotions or spam), start here.
Free plan: 500 subscribers, unlimited sends, automation, landing pages, 700+ templates.
Paid: Lite from $15/mo (unlimited subscribers on annual billing).
Best for: Solo founders who need reliable inbox placement and are writing to corporate email addresses.
2. MailerLite — Best Free Plan for Beginners

MailerLite gives you 1,000 free subscribers, which is twice AWeber. The interface is the cleanest of any email tool in this category. If you have never set up email marketing before, MailerLite is the fastest path from zero to first email sent.
The free plan includes automation workflows, 10 landing pages, pop-ups, and A/B testing. Most tools charge for this. MailerLite does not on the free tier.
Free plan: 1,000 subscribers, 12,000 sends/month, automation (1 workflow), 10 landing pages, pop-ups, A/B testing.
Paid: Growing Business from $9/mo (unlimited emails).
Best for: First-time email marketers who want the most capable free plan in the category.
3. GetResponse — Email + Landing Pages Combined

Beehiiv is email-only. GetResponse is email plus landing pages plus automation funnels. For solo founders who do not want three separate tools, GetResponse consolidates the stack under one login.
The free plan includes one landing page on a custom domain — something no other tool in this list offers free. If you are distributing lead magnets or driving traffic to a product page, GetResponse removes the need for Leadpages or a separate builder.
Free plan: 500 contacts, unlimited newsletters, 1 landing page (custom domain), sign-up forms, basic automation.
Paid: Email Marketing from $15.58/mo.
Best for: Solo founders who want email + landing pages without managing separate tools.
4. Flodesk — Best Email Design

Flodesk makes the most beautiful emails. Period. If you are building a premium B2B newsletter where design signals credibility, Flodesk produces brand-consistent, editorial-quality emails that no other tool at this price point matches.
The unusual pricing: flat $38/month regardless of subscriber count. Expensive at 100 subscribers. The cheapest option in the market at 10,000 subscribers.
Plan: 30-day free trial (full access), then $38/mo flat (unlimited subscribers, unlimited sends, checkout pages for digital products).
Best for: B2B creators where email design is central to brand positioning and you expect to grow past 5,000 subscribers.
5. Beehiiv — If You Want to Monetize Your Newsletter
Beehiiv is not primarily an email marketing tool — it is a newsletter platform with built-in monetization: a native ad network, paid subscriptions, and a referral program. If newsletter revenue (not just affiliate revenue) is your goal, Beehiiv is worth the $42/mo.
If you just want to send emails to drive affiliate income, the tools above are cheaper and better for that use case.
Free plan: 2,500 subscribers (best free tier by volume).
Paid: Scale from $42/mo.
Best for: Creators who want built-in newsletter monetization and a referral program.

Frequently Asked Questions
What email marketing tool is free for small lists?
AWeber (500 subscribers), MailerLite (1,000 subscribers), and GetResponse (500 contacts) all have permanent free plans. Not trials — free until you exceed the limit.
What is the best email tool for B2B?
AWeber for deliverability to corporate email addresses. MailerLite if you are just starting and want the most capable free plan. GetResponse if you also need landing pages.
Is Mailchimp worth it for solo founders?
No. Mailchimp’s free plan became significantly less useful after they removed automation in 2023. MailerLite or AWeber offer more for free.
Bottom Line
Start free. Upgrade when your list justifies it. Every tool in this list has a free or trial entry point — there is no reason to pay before you have 500 subscribers.
For most B2B solo founders writing content and building an email list: start with AWeber (best deliverability) or MailerLite (most capable free plan). Both are free until you hit 500–1,000 subscribers, which buys you 6–12 months to validate the newsletter before paying anything.
