Every B2B marketing guru in your LinkedIn feed is screaming about HubSpot ($800/month), ActiveCampaign ($149/month), or Klaviyo ($150+/month). Meanwhile, you’re a 3-person shop in Bergen County trying to figure out how to send a monthly newsletter without taking out a small business loan. Here’s the truth nobody selling you software wants you to hear: you can build a functional B2B email marketing stack for $0 — and run it that way until you have real revenue justifying an upgrade.
The three free pieces
You need three things to do B2B email marketing: a way to capture leads, a place to store them, and a way to send messages. That’s it. Everything else the SaaS world tries to sell you is bolt-ons. Here’s the minimum viable stack:
- Mailchimp Free — Send to up to 500 contacts, 1,000 emails per month. That covers a startup’s entire first year for most B2B shops in Bergen County. Drag-and-drop builder, decent templates, basic automation included.
- Google Forms — Embed on your site as a lead-capture form. Free. Unlimited submissions. Pipes responses into a Google Sheet automatically. Native integration with Mailchimp via Zapier free tier (100 tasks/month).
- Notion CRM — Free for personal use, generous limits. Build a contact database with deal stage, last contact, next action, lead source. Better than a spreadsheet, easier than Salesforce. Replaces a $50/month HubSpot CRM seat.
How the pieces fit together
Prospect lands on your site. They fill out a Google Form (embedded on your contact page). The response writes to a Google Sheet AND triggers Zapier to add them to a Mailchimp list. You manually copy hot leads into your Notion CRM with a deal stage. Mailchimp sends your monthly newsletter automatically. Notion is where you track the deals that matter. Total cost: $0/month, indefinitely.
What you get for free that people pay $500/month for
- Email automation. Mailchimp’s free plan includes a welcome series and one automation flow. Enough to send “thanks for downloading” emails automatically.
- Open + click tracking. Full analytics on every campaign — opens, clicks, bounces, unsubscribes. Same data HubSpot charges $800/month for.
- List segmentation. Tag contacts by source, industry, deal size. Send targeted campaigns to subsets without paying for “advanced” tiers.
- A/B testing. Test subject lines on subsets of your list. Free on Mailchimp’s free plan.
- Branded templates. Drop your logo, set your brand colors once, every send looks consistent. No designer needed.
When to graduate to paid tools
The free stack works until it doesn’t. Here are the specific signals that mean it’s time to spend money — not before.
- You hit 500 contacts. Mailchimp’s free tier caps there. Upgrade to Essentials ($13/month for 500–1,500). Don’t jump to ActiveCampaign yet — finish using what you’ve got.
- You’re sending 4+ campaigns per month. The 1,000-email-per-month cap will bite. Same upgrade path.
- You need multi-step automations. If a single welcome flow isn’t enough — say you’re nurturing leads through a 6-email sequence — graduate to Mailchimp Standard ($20/month) or ConvertKit ($25/month).
- You’re hitting Zapier’s 100-task-per-month free cap. Either pay Zapier ($20/month) or switch to a tool with native integrations.
- Sales pipeline tracking outgrows Notion. When you’ve got 50+ active deals and multiple salespeople, Notion CRM creaks. That’s when HubSpot’s free CRM (yes, also $0) makes sense, or Pipedrive at $15/seat.
The mistake most B2B shops make
Buying tools before they have a list. Don’t subscribe to a $150/month email platform when you have 47 contacts. Get to 500. Get to 5 campaigns. Then pay for the upgrade that actually solves a bottleneck you’ve hit. Most B2B shops in Bergen County waste $2,000–$5,000 a year on email tools they don’t use because they bought the dream, not the workflow.
How AJD handles this
For clients under 500 contacts, we set up exactly this stack — Mailchimp + Google Forms + Notion — and we don’t charge a recurring fee for it. We build the templates, write the welcome flow, and hand it over. Whether you work with us or not, start with $0. Build the list first. Pay for tools only when you’ve outgrown the free ones, not before.
