Cost depends mainly on three factors : the size of your contact list, the level of automation you need, and whether you already have email content/design or it needs to be built from scratch. There's no single market price — but there is a clear way to estimate it.
The 3 factors that determine price
1. List size
Email marketing platforms charge by number of active contacts. A bigger list means a higher tool cost — regardless of the AI layered on top of it.
2. Automation level
Setting up basic segmentation is faster and cheaper than designing full sequences with dynamic personalization and ongoing behavior-based optimization.
3. Content and design
If you already have email templates and brand copy, the cost concentrates on automation setup. If content needs to be created from scratch, that adds to the project.
What a full implementation typically includes
- Audit of your list and cleanup of inactive contacts
- Behavior-based segment setup
- Design of at least one automated sequence
- Integration with your existing CRM or capture form
- Results report with real metrics
Why it's worth quoting based on your specific case
A business with 500 contacts and a single welcome sequence has a very different need — and cost — than a company with 20,000 contacts and several sales teams. Any price published without knowing these details is, at best, a general reference.
How it compares to other lead-generation channels
AI email marketing usually has a lower monthly operating cost than paid channels, because it relies on contacts who already engaged with your brand instead of paying for every new click.
Frequently asked questions
Does the price include the email marketing platform?
It depends on the project — some quotes include the platform inside the monthly package, others quote setup separately.
Is there a minimum cost to get started?
The minimum cost, in MXN, varies based on your list size and whether you need new content or just setup.
Can I start small and grow later?
Yes. It's common to start with one well-configured automated sequence and expand to more segments as results come in.
