Make the smallest decision that fixes the named constraint.
Choose HubSpot when company, contact, deal stage, owner, next action, and sales history must remain one durable record. Its Free tools support up to two users, one deal pipeline, and 2,000 branded marketing-email sends per calendar month. That makes it a defensible zero-cost starting point for a sales-led consultancy.
Choose MailerLite when the durable object is the permissioned subscriber and the main work is campaigns, forms, landing pages, and visual nurture. Free is limited to 250 active subscribers and 2,500 monthly sends; Comfort starts at $12 per month. Neither product should be forced to imitate the other through manual notes and disconnected exports.
Decision snapshot
Free documents one deal pipeline, up to two users, and CRM-connected sales and marketing tools.
Free documents 250 active subscribers; Comfort adds larger limits and removes several production constraints.
HubSpot’s non-promotional Starter reference and MailerLite Comfort floor; live tiers and terms control.
Scenario: 400 opted-in contacts and 20 live consulting opportunities
The consultant sends four full-list emails monthly and needs a visible next action for each active opportunity.
Assumptions
- Four 400-recipient broadcasts consume 1,600 sends per month before automation.
- Twenty opportunities need stage, value, next action, and history.
- One person operates the system; no ecommerce catalog or paid newsletter is required.
Disclosed math
- HubSpot Free send headroom: 2,000 − 1,600 = 400 sends, before automation.
- MailerLite Free is unavailable at 400 active subscribers; Comfort starts at $12 × 12 = $144.
- HubSpot Starter planning baseline for one seat is $20 × 12 = $240 before temporary offers.
Result: Use HubSpot Free if opportunity follow-up is the critical failure mode and 400 sends of monthly headroom are enough. Use MailerLite Comfort if the pipeline is simple elsewhere and the campaign/automation program needs more room. Do not buy both until a documented handoff exists.
Scenario outputs are arithmetic from the assumptions above, not traffic, conversion, revenue, or savings forecasts.
Use these decision criteria
Name the durable record
If losing a next action costs more than losing a campaign branch, center the stack on CRM. If consent, sequence state, and audience segments are primary, center it on email.
Forecast send headroom
HubSpot Free’s 2,000-send ceiling can become tight at 400 contacts. MailerLite Comfort’s allowance scales at ten times its subscriber-tier ceiling.
Design one handoff
If both tools are eventually required, define the event that crosses systems—such as qualified lead or signed client—and one owner for consent state.
Choose, pause, or reject
| Option | Choose when | Pause when |
|---|---|---|
| Choose HubSpot | Deals, companies, owners, and next actions are the operating center and email volume is modest. | The business mainly publishes and nurtures a broad audience with few active deals. |
| Choose MailerLite | Campaigns, subscriber journeys, forms, and landing pages matter more than a structured deal pipeline. | Sales follow-up is already disappearing into tags or free-text notes. |
| Use both later | A validated audience-to-qualified-lead handoff has one direction, one consent owner, and a reconciliation process. | The integration would merely duplicate every record and create two competing truths. |
Run the same ten-lead acceptance test
- Create ten test contacts with distinct consent and lifecycle states.
- Capture each through the real form and deliver one nurture message.
- Mark three as qualified, schedule follow-up, and change one email address.
- Export the records and verify that consent, stage, next action, and sequence state remain understandable.
Pass rule: The winner is the product that preserves the information the next human action requires with fewer manual fields and fewer ambiguous owners.
Limits to keep visible
- The products have different data models; feature counts do not make them interchangeable.
- Prices exclude possible taxes and can change with contacts, seats, term, or promotion.
- No deliverability or usability result is implied by this documentation comparison.

Frequently asked questions
Is MailerLite a replacement for HubSpot CRM?
Not when a structured company and deal record is essential. MailerLite can manage subscribers and automation, but this comparison treats HubSpot as the deal-centered system.
Can HubSpot Free replace MailerLite?
For a small, sales-led list it can cover forms and branded marketing email within its limits. A larger publishing or automation program can reach the Free send and automation boundaries quickly.
Should a consultant use both HubSpot and MailerLite?
Only after defining the qualification handoff, consent owner, synchronization direction, duplicate rule, and exit process. Two tools without that contract create two sources of truth.
