Make the smallest decision that fixes the named constraint.
Start with Comfort when three users, 50 active automations, ten forms, and ten combined websites or landing pages are enough. Comfort starts at $12 per month and its send allowance is ten times the ceiling of the purchased subscriber tier. For an up-to-1,000 tier, that means 10,000 sends per month even if the live list is smaller.
Choose Power when the workload—not the marketing label—requires unlimited sends under fair use, unlimited users, unlimited active automations and assets, multiple automation triggers, or 24/7 live chat. Power starts at $25 per month, a $156 annual starting-price gap from Comfort.
Decision snapshot
Three seats, 50 automations, ten forms, and a 10× subscriber-tier send allowance are documented.
Unlimited sends under fair use, unlimited seats, automations, forms, sites, and digital products are documented.
($25 − $12) × 12, before subscriber-tier adjustments, tax, or annual discounts.
Scenario: 800 subscribers, weekly dispatch, and an active nurture library
A three-person agency sends four full-list newsletters and delivers an average of seven automation emails per subscriber each month.
Assumptions
- The account sits in an up-to-1,000 subscriber tier.
- Four broadcasts consume 800 × 4 = 3,200 sends.
- Seven automation messages across the active list consume up to 800 × 7 = 5,600 sends.
Disclosed math
- Estimated demand: 3,200 + 5,600 = 8,800 sends per month.
- Comfort allowance at the 1,000 ceiling: 1,000 × 10 = 10,000 sends.
- Remaining modeled headroom: 10,000 − 8,800 = 1,200 sends.
Result: Comfort still fits, but the 12% headroom is thin. Set a review at 9,000 forecast sends or before adding another recurring sequence. Power is justified when the production calendar will cross the allowance—not simply because unlimited sounds safer.
Scenario outputs are arithmetic from the assumptions above, not traffic, conversion, revenue, or savings forecasts.
Use these decision criteria
Forecast sends, not campaigns
One campaign to 800 people consumes 800 sends. Include automated messages, resends, and seasonal peaks in the same model.
Separate seats from client accounts
Power’s unlimited users may matter to an agency team, but it does not automatically solve client-data separation or governance. Confirm the intended account structure.
Inventory active assets
Comfort’s limits are generous for one firm. An agency operating many brands, forms, or funnels can hit active-asset limits before it hits send volume.
Choose, pause, or reject
| Option | Choose when | Pause when |
|---|---|---|
| Choose Comfort | The forecast stays below the 10× send allowance and the team fits inside three seats and published asset limits. | A known launch month or new automation will consume the remaining buffer. |
| Choose Power | Unlimited sends, users, active assets, multiple triggers, or live-chat support removes a current production constraint. | The account uses only a fraction of Comfort and has no owner for the extra capability. |
| Split client work | Client consent, ownership, billing, and export requirements call for separate accounts rather than a larger shared plan. | Duplicated administration would cost more than the governance benefit. |
Stress-test one real high-volume month
- Export the previous 90 days of sends and calculate the highest month.
- Add every planned automation message and resend for the next campaign cycle.
- Count active users, automations, forms, sites, landing pages, and digital products.
- Test a subscriber export and document who owns each client list.
Pass rule: Power passes when the verified high-month workload exceeds a Comfort boundary or the cost of throttling and manual coordination exceeds the confirmed price difference.
Limits to keep visible
- Both paid prices are published as starting points; exact tiers and taxes must be checked.
- Power’s unlimited sending remains subject to MailerLite’s fair-use policy and acceptable-use rules.
- This comparison does not establish deliverability for a domain, list source, or sending pattern.

Frequently asked questions
How many emails can MailerLite Comfort send?
Comfort allows ten times the ceiling of the purchased subscriber tier each month. An up-to-1,000 tier therefore carries 10,000 sends, not ten times the exact live count.
Is MailerLite Power unlimited?
Power documents unlimited monthly email sends and unlimited active assets, but sending is subject to fair use and product terms.
When is the $13 monthly upgrade gap worth it?
When a named Comfort limit will interrupt a production workflow or when the operational value of added users, support, or assets exceeds the confirmed checkout difference.
