Small business marketing automation usually means one of four jobs. HubSpot Starter ($20/mo) handles CRM and pipeline, Mailchimp ($13/mo) or ActiveCampaign ($29/mo) run email, Omnisend ($16/mo) covers ecommerce email and SMS, and Zapier ($19/mo) glues tools together. theStacc ($99/mo) produces the content itself.
"Marketing automation" covers three very different jobs. Content automation (theStacc) writes and publishes for you. Email automation (Mailchimp, ActiveCampaign) sends sequences when someone subscribes. CRM automation (HubSpot) routes leads and updates pipelines. Buying the wrong category is how small businesses end up with $300/mo of unused dashboards.
We tested 10 tools over 90 days on three small businesses — a B2B SaaS, a local services brand, and a Shopify store. Here is the ranking by what each tool actually removes from your week.
You hate writing content: theStacc ($99 content, $167 bundled). You need CRM + pipeline: HubSpot Starter ($20). Email-first business: Mailchimp ($13) or ActiveCampaign ($29). E-commerce email/SMS: Omnisend ($16). Cross-tool glue: Zapier ($19). Tightest budget: Brevo, MailerLite, Buffer (all have free tiers).
Want content marketing on autopilot?
theStacc writes 30 SEO articles a month, publishes them to your CMS, posts to GBP, and pushes to social. $167/mo bundled — one tool replaces five.
The 4 categories of marketing automation
Every "marketing automation tool" lives in one of four buckets. Buy by the bucket your business is missing:
- Content automation — theStacc. Research, write, publish, distribute.
- Email and SMS automation — Mailchimp, ActiveCampaign, MailerLite, Omnisend, Brevo.
- CRM and pipeline automation — HubSpot. Lead routing, deal stages, follow-up sequences.
- Cross-tool and social automation — Zapier, Buffer, CoSchedule.
"One platform for everything" sounds like a deal until you realise you are paying for an email tool, a CRM, and a content module — and the content module is the weakest in every all-in-one. Most small businesses end up better off with a specialised content tool plus a specialised email tool plus a free CRM.

theStacc Bundle at $167/mo handles blog content, GBP posts, and social distribution. Keep your email tool, keep your CRM, drop the freelancer and three scheduling tools.
9-point evaluation checklist
- Category fit — content, email, CRM, or workflow glue?
- Free tier — usable for your first 500 contacts?
- Automation depth — broadcast only or conditional logic?
- CRM included — or do you need a separate one?
- Native integrations — your CMS, ecom platform, ad tools?
- Pricing scale — does it spike at 5K contacts?
- Reporting — attribution to revenue, not just opens?
- Onboarding — DIY or human help included?
- Cancellation — monthly or annual lock?
How much should you actually pay?
$ Right-fit pricing
- Pre-revenue, <500 contacts: Free — HubSpot CRM + Brevo + Buffer
- Solo operator, basic email: $13–$29 (Mailchimp, ActiveCampaign)
- Owner without a marketing team: $167 (theStacc Bundle)
- Small business with 1 marketer: $200–$300 stack
- Ecom store under $1M: $16–$60 (Omnisend + theStacc Content)
$ Common overpayment traps
- HubSpot Pro at $890/mo when Starter does the job
- Paying for "AI content" inside a CRM you already pay for separately
- Per-seat tools when only one person uses them
- Annual lock-ins before you have validated ROI
- Per-contact email pricing past 10K when flat-fee tools exist
DIY automation stack vs done-for-you with theStacc
HubSpot + Mailchimp + Buffer + a writer
- HubSpot Starter ($20) for CRM and forms
- Mailchimp ($39) or ActiveCampaign ($49) for email
- Buffer ($30) for social scheduling
- Freelance writer at $80–$250 per article
- Zapier ($19) to stitch the four tools together
- You still own the briefs, edits, and publishing
theStacc Bundle for the content side
- 30 SEO articles a month, auto-published
- Weekly GBP posts written and scheduled
- Social posts auto-generated from each article
- Keep HubSpot Starter ($20) for CRM
- One invoice replaces five tools and the freelancer
- Cancel anytime — no contract
Final verdict — which tool to pick
- You want content marketing off your plate: theStacc ($99/mo, $167 bundled).
- You need a free CRM that grows with you: HubSpot Starter ($20/mo).
- You want easy newsletters and broadcasts: Mailchimp ($13/mo).
- You run multi-step lifecycle email: ActiveCampaign ($29/mo).
- You run a Shopify store: Omnisend ($16/mo).
- You need to glue 4 SaaS tools together: Zapier ($19/mo).
If you are a small business owner without a marketing team, the biggest weekly time sink is content — not email. Run HubSpot Starter (free CRM) plus Mailchimp ($13) plus theStacc Bundle ($167) for around $200/mo. That replaces a $1,200/mo marketing hire on the channels that matter for organic growth.
Frequently asked questions
It depends on what you need automated. For content marketing on autopilot, theStacc ($99/mo for content, $167/mo bundled). For full CRM and pipelines, HubSpot Starter ($20/mo). For email-led automation, Mailchimp or MailerLite ($13 to $39/mo). For deep email workflows, ActiveCampaign ($29/mo).
If you have any recurring marketing task — sending a newsletter, posting on social, publishing blogs, responding to leads — automation pays back inside a quarter. The wrong question is "do I need it"; the right one is "which task is eating my Friday."
HubSpot Starter is $20/mo and covers email, forms, and a basic CRM. The cost trap is upgrading to Marketing Hub Pro at $890/mo before the free CRM has paid off. Most small businesses live happily on Starter for 12 to 18 months.
Mailchimp is broader and easier — email plus light automation plus landing pages plus social ads. ActiveCampaign is deeper on automation — conditional logic, lead scoring, sales pipeline triggers. If your marketing is mostly newsletters, Mailchimp. If it is multi-step lifecycle, ActiveCampaign.
For under 500 contacts, yes. Brevo, Mailchimp, MailerLite, and HubSpot all have generous free tiers. The free-plan limit usually hits at 2,000 contacts or when you need conditional automation, not when you need volume.
theStacc automates the content side of marketing — blog research, writing, publishing, internal linking, GBP posts, and social. It does not replace HubSpot for CRM or Mailchimp for transactional email. Most operators run theStacc plus one email tool plus a free CRM.
Under $200/month total for the stack. A common right-sized setup: HubSpot Starter ($20) plus Mailchimp ($39) plus theStacc Bundle ($167) covers CRM, email, content, GBP, and social. That is roughly $226/mo for what would otherwise be a full-time marketing hire.
