Marketing Automation Tools Under $100/Month for Solopreneurs

You don't need an enterprise platform to run a real marketing operation. For a one-person business, a stack of marketing automation tools under $100/month isn't a compromise. It's the right call. Freemium pricing is everywhere in 2026, and AI assistance is built into plans that cost less than a dinner out. The core stack in this guide comes to about $76 a month on yearly billing, or about $90 billed monthly, with every price taken from the vendor's own pages as of September 2026. You'll see exactly what to buy, what to skip, and how to wire it all together in about four weeks.

What Your Stack Actually Needs

Before picking tools, get clear on the layers. A working solopreneur marketing stack covers six things:

• Email marketing and automation (your core revenue channel)
• CRM or contact management (knowing who your leads are)
• Landing pages and forms (capturing those leads)
• Social scheduling (staying visible without babysitting every post)
• Automation glue (connecting tools without code)
• Analytics (knowing what's working)

That's it. You don't need a dedicated webinar platform, a CDP, a six-channel ad manager, or a custom attribution model. Those are problems for when you have a team. Right now, six layers, kept lean, is the whole game.

Cost Reality Check

Entry-level paid email plans for 500 to 1,000 contacts run about $9 to $39 a month as of September 2026 (Brevo, MailerLite, Mailchimp and Kit, billed monthly). At the team end, HubSpot's pricing guide lists Marketing Hub Professional at $800 a month billed yearly, plus a $3,000 onboarding fee. The easy way to overspend is buying tools designed for 10-person marketing teams.

The fix is to match tool complexity to your actual list size and workflow needs. Under 5,000 contacts, entry plans cover most of it: Systeme.io's free plan includes 2,000 contacts with unlimited email, and Startup covers 5,000 for $17 a month billed monthly. Use free plans where they're enough, pay only where they aren't, and the whole stack stays under $100 a month.

A stack that runs your welcome sequences, lead nurture, and social posting isn't a budget hack. It buys back your time.

The Core Stack: What to Buy

Here is a concrete configuration that comes to about $76 a month on yearly billing. Every figure is the vendor's own price as of September 2026, so you can check any row against its pricing page:

Billed month to month, the same plans come to about $90: Systeme.io $17, MailerLite $12, Notion $12, Make $10.59, Plausible $9 and Tally $29. Make's row uses its standard price (see Automation Glue for its test pricing). Canva Pro is an optional upgrade, covered in the design section below.

Not every solopreneur needs this exact combination. Pay only where the free tier breaks, and two rows become optional: Systeme.io already sends unlimited email, so MailerLite is only worth adding if you want your newsletter separate from your funnels, and Tally's free plan covers unlimited forms with conditional logic. Drop both and you pay about $41 a month billed yearly, or about $49 billed monthly.

Email: Your Revenue Engine

Email is where automation pays off fastest. A welcome sequence and a basic nurture flow keep working after you stop touching them, which no manual social campaign does. At this budget, let price and limits decide. Prices below are as of September 2026.

MailerLite is the default pick because its entry paid plan pairs a low price with 50 automations and 10 landing pages. That plan is now Comfort, which replaced Growing Business in 2026: $12 a month billed monthly, or $10.80 a month billed yearly, for up to 500 subscribers. The free plan covers 250 subscribers, 2,500 emails a month, and three automations, which is enough to get started.

Brevo (formerly Sendinblue) takes a different approach: its free plan stores up to 100,000 contacts but sends only 300 emails a day, and just 2,000 contacts can enter automations. Paid Starter plans begin at $9 a month billed monthly for 5,000 emails and up to 500 stored contacts. If your list is large but you send infrequently, the free plan is the draw.

Mailchimp Standard is $20 a month for 500 contacts, billed monthly, and the price climbs with every contact tier. The free plan now stops at 250 contacts and 500 sends a month. Use it if you're already on it; on price alone, don't start there.

Kit (formerly ConvertKit) has a free plan for up to 10,000 subscribers, but sequences and visual automations need a paid plan; Creator starts at $39 a month billed monthly for 1,000 subscribers. It's built for creators, so if you're a coach or course creator, Kit fits the workflow.

HubSpot Marketing Hub Starter bundles email, forms, live chat, and ad management with 1,000 marketing contacts on the free HubSpot CRM. It's also included in the Starter Customer Platform, listed at $20 per seat per month, which new customers currently get for a limited-time $7 a seat per month billed yearly, or $10 month to month. If you want email plus basic CRM in one tool, this is the simplest route.

CRM: Don't Overcomplicate It

At the solopreneur stage, your email tool is often your CRM. MailerLite, Kit, and Brevo all let you tag, segment, and track contacts well enough to manage a lead pipeline without a separate CRM.

If you want a dedicated CRM, start with HubSpot's free CRM. It costs nothing, covers contact management, deal tracking, and a basic pipeline view, and connects directly to HubSpot's email tools. Adding Marketing Hub Starter puts the whole email-plus-CRM layer at one Starter seat, no more than $20 a month at list price.

Don't buy a paid CRM until you're managing more leads than you can track in your email tool. That threshold is higher than you think.

Landing Pages and Forms

Most email platforms include landing page builders (MailerLite's free plan has one), and Systeme.io covers full funnel pages. For something standalone, Carrd is free for up to three sites, and its Pro plans are priced per year, not per month.

For forms, Tally's free plan already includes unlimited forms and submissions (within fair use) and conditional logic. Tally Pro costs $29 a month or $290 a year and adds branding removal, custom domains, partial submissions, and team collaboration. Google Forms also works for basic data collection.

Stop Doing Social Posting Manually

Manually posting to three platforms every week is a time sink that scheduling mostly removes.

Buffer's free plan connects up to three channels with 10 scheduled posts per channel at a time, plus a content calendar and its AI Assistant. Essentials lifts the post cap for $5 per channel per month billed yearly, or $6 billed monthly. That's it. You don't need a bigger social media suite at this stage. Schedule your posts, move on.

Automation Glue

Make (formerly Integromat) Core is $9 a month billed yearly, or $10.59 billed monthly, for 10,000 credits a month. Some visitors currently see a higher test price ($12 billed yearly, $16 monthly); the totals in this guide use the standard price. Make has billed in credits instead of operations since August 2025, and most module actions use one credit. It connects your tools without code, and the free plan (1,000 credits a month) lets you test a scenario before paying. If you're deciding between Make and n8n for more complex setups, read the n8n vs Make comparison for complex marketing workflows.

Zapier works too: 100 free tasks a month on two-step Zaps, and paid plans from $19.99 a month billed yearly for 750 tasks. At low volumes, Make's credits go further, though Zapier doesn't charge for triggers.

Design on a Budget

Canva's free plan covers email graphics, social posts, lead magnets, and presentation decks, with one Brand Kit and 1.6 million templates. Canva Pro adds the background remover, up to five Brand Kits, and 3.6 million templates. Pro's price varies by country and billing period, so check Canva's pricing page for yours, and upgrade when you regularly need those extras.

Analytics: Free Is Fine

GA4 and Google Search Console cover website and organic search measurement at zero cost. Plausible starts at $9 a month billed monthly for one site, or $90 billed yearly, after a 30-day free trial. Plausible says it uses no cookies and collects no personal data, so it needs no cookie banner, though it tells customers to confirm that with a legal advisor. Pick one and actually check it weekly. The tool doesn't matter as much as the habit.

A Second Stack Worth Knowing

If content creation is your biggest bottleneck, spend on writing instead of funnels: Claude Pro ($20 a month, or $200 a year), MailerLite's or Brevo's free plan for email (beehiiv's free plan has no automations), Buffer's free plan, Canva Free, Notion Plus ($10 a month billed yearly, or $12 billed monthly), GA4, and Zapier's free plan for connections. That's about $27 a month on yearly billing or $32 billed monthly. Add Buffer Essentials on three channels and those become about $42 and $50.

This configuration solves a different problem than the Systeme.io-centered stack. Both land under $100 a month, even billed monthly. Choose based on where you're losing the most time.

Build It in 4 Weeks

Don't implement everything at once. A week-by-week rollout keeps the setup manageable and gets your first automation live before you add more tools.

Week 1: Pick your email tool and CRM. Import your existing contacts. Set up basic segmentation (leads vs. customers is enough to start). Don't build any automations yet.

Week 2: Build your welcome sequence. Three to five emails, triggered by a form submission or opt-in. It's the first automation worth building, so get it live before anything else. Monitor open rates and click rates from day one.

Week 3: Connect your landing page and form to the email workflow. Set up Buffer and build two weeks of scheduled social content. Wire Make to connect your form tool to your email platform if they don't integrate natively.

Week 4: Set up GA4 or Plausible. Start A/B testing subject lines where your plan allows it. Add an AI writing tool if content creation is slowing you down. Review every tool you've paid for and confirm it's earning its cost.

Example: How the $76 Stack Fits Together

A consultant running a lead generation funnel might wire it like this: Systeme.io handles the funnel pages and email sequences, Tally captures leads from a free resource download, Make passes those leads into MailerLite and tags them by source, Buffer's free plan queues LinkedIn posts three times a week, Canva's free plan handles the lead magnet design and email graphics, and Plausible tracks which landing pages convert best.

Total: about $76 a month on yearly billing. After setup, the manual work is writing content and reviewing metrics. The automations handle the hand-offs, so you can focus on strategy and client delivery. For the lead-capture side, see how to build an automated lead generation workflow.

Common Pitfalls

Overbuying features. The most expensive mistake is buying a platform at the tier designed for a 10-person team because you might need it someday. Start at the lowest paid tier and upgrade when you hit an actual limit.

Redundant tools. If your email platform has a landing page builder, you don't also need a standalone landing page tool. If your CRM has email, you don't need a separate email platform. Audit for overlap before you add anything.

Over-integrating. Make and Zapier make it easy to build elaborate multi-step workflows that break silently and take hours to debug. Build simple automations first. A welcome sequence triggered by a form submission is more valuable than a 12-step behavioral workflow you built in week one and never tested properly.

Ignoring free tiers. Several tools here have free plans that cover real work: HubSpot's free CRM, Buffer (three channels), Canva Free, Tally, GA4, Google Search Console, and Cal.com. Use them until you hit the limit. Don't pay for features you're not using.

When to Scale Up

The right time to upgrade a tool is when you hit a hard limit that's costing you money or time. Specific triggers:

• Email platform: Upgrade when your list size pushes you into the next pricing tier and the cost is justified by revenue from those contacts.
• CRM: Upgrade from free to paid when you're managing more than a few dozen active deals and the free tier's pipeline views aren't enough.
• Automation glue: Upgrade Make when you're hitting your monthly credit limit regularly.
• All-in-one switch: Consider moving to ActiveCampaign or HubSpot's higher tiers when you have a team or when managing multiple separate tools creates more overhead than it saves.

Don't switch platforms because a competitor's feature list looks impressive. Switch when your current tool is actively blocking revenue.

Frequently Asked Questions

Start Simple, Stay Under Budget

A focused stack is easier to run than a bloated one. Welcome sequence, lead nurture, social scheduling, clean analytics: for a one-person business, that covers the core of the operation.

Pick one email tool, wire in a form, build a three-email welcome sequence, and schedule two weeks of social posts. Do that before you add anything else. A complete stack for solopreneurs isn't about having every tool. It's about having the right ones running reliably while you focus on the work that actually generates revenue. Every tool in the core stack has a free plan or a free trial. Start there, prove the workflow, then pay.
