Quick Answer
The cheapest marketing automation in 2026 depends on list size and channel needs: Brevo starts at $9/month, Mailchimp at $13/month, and ActiveCampaign at $15/month for small lists — but all three scale steeply with contact count, so a 50,000-contact list costs hundreds per month. A flat-fee owned CRM at $48/month bundles unlimited email plus SMS, booking, and funnels with no per-contact pricing, making it the cheapest option at scale and the only one that includes multi-channel marketing in the base price. For service businesses with growing lists, the owned CRM's flat fee wins on total cost within the first year.
Key Takeaways
- Brevo at $9/month is the cheapest entry point, but a flat-fee owned CRM ($48/month) is cheapest at scale because it bundles email, SMS, booking, and funnels with no per-contact pricing.
- Brevo, Mailchimp, and ActiveCampaign offer free tiers capped at a few hundred contacts — useful for testing, but they force paid upgrades fast as the list grows.
- Mailchimp starts at $13/month but scales to $350+/month based on contact count and features — see our [best email marketing software 2026](/blog/best-email-marketing-software-2026) comparison.
- Yes — a flat-fee owned CRM ($48/mo) bundles email, SMS, online booking, and funnels, while Brevo, Mailchimp, and ActiveCampaign charge separately for SMS or do not include booking.
- Around 2,000–5,000 contacts the per-contact tools cross $48/month, making the flat-fee owned CRM cheaper — and the gap widens as the list grows.

Cheap entry price vs cheap total cost
The cheapest starter plan rarely stays cheap — per-contact pricing means cost climbs as your list grows, which is when you need automation most.
Marketing automation pricing has two failure modes: a cheap starter price that explodes with list growth, and a cheap price that excludes the channels (SMS, booking) you actually need. The honest comparison looks at total cost at your real list size and channel needs, not the entry tier. Our best marketing automation software 2026 and best email marketing software 2026 guides cover the category; this is the cost-focused comparison.
Cheapest marketing automation comparison (2026)
Compare entry price, cost at 10k contacts, and bundled channels to find the real cheapest option.
| Platform | Entry price | Cost at 10k contacts | SMS included | Booking included |
|---|---|---|---|---|
| Brevo | $9/mo | $60–$120+ | Paid add-on | No |
| Mailchimp | $13/mo | $100–$350+ | Paid add-on | No |
| ActiveCampaign | $15/mo | $145–$250 | Paid add-on | No |
| MailerLite (free tier) | Free (≤1k) | $70–$140 | No | No |
| Owned CRM ($48/mo) | $48 flat | $48 flat | Yes | Yes |
The owned CRM's flat fee is the structural cost advantage: it never scales with contacts, and it bundles SMS and booking that the others charge extra for or omit. See our how much does CRM cost and marketing agency vs in-house cost comparisons.
When each option is actually cheapest
Match the tool to your list-size trajectory and channel needs to find the real cheapest option for your situation.
- Brevo: cheapest for very small lists under ~1,000 contacts where the $9 tier holds.
- MailerLite free tier: free up to 1,000 contacts for email-only testing.
- ActiveCampaign: cheapest if you need deep automation logic but not other channels.
- Owned CRM: cheapest at 2,000+ contacts and the only one bundling SMS + booking + funnels.
- Mailchimp: rarely cheapest at scale — its pricing climbs steeply with contacts.
Setting up the owned CRM's multi-channel automation requires CRM configuration. Teams needing platform administration can hire a virtual assistant, and CRM expert VAs specialize in this build.
