THE SHORT ANSWER
Our conclusion
Choose Kit for a 1,200-reader newsletter that must go out together. Brevo remains a candidate for smaller daily customer batches and a larger stored database. Do not choose Brevo simply because its contact number looks larger; the send schedule decides this comparison.
Side-by-side comparison
Read across each row: the same criterion, two approaches and the practical consequence. Capabilities describe the product offering, not a promise that every free or entry plan includes them.
| Criterion | Kit | Brevo | What this means for you |
|---|---|---|---|
| Free audience/database | 10,000 subscribers | 100,000 stored contacts | Compare active readers with actual daily recipients. |
| Broadcast allowance | Unlimited email broadcasts | 300 email sends per day | Kit fits a larger same-day newsletter. |
| 1,200-reader issue | Within published broadcast capacity | At least four sending days at full daily capacity | Choose Kit if the whole issue must arrive the same day. |
| 180 updates plus 40 welcomes | Capacity is not the obvious obstacle | 220 total fits the daily cap | Exact automation availability remains a separate question. |
| Growth constraint | Required automation or other paid capabilities | Daily sending deadline may force an upgrade | Price the first constraint your workload will reach. |
Strengths and trade-offs
Kit
Why choose it: Larger same-day newsletter capacity on the free offer.
Trade-off: Broadcast capacity does not verify an advanced automation workflow.
Brevo
Why choose it: A large contact database with modest daily sends.
Trade-off: A large stored list can still take many days to contact.
Make the decision with your own evidence
Choose the two criteria below that matter most to your work. Run the same small task in both products and record a pass, a fail or an unresolved question. An untested requirement is unknown, not a pass. A failed must-have outweighs optional extras.
| Criterion to test | What to record for each product |
|---|---|
| Free audience/database | Compare active readers with actual daily recipients. Record the exact plan, observed result and any workaround. |
| Broadcast allowance | Kit fits a larger same-day newsletter. Record the exact plan, observed result and any workaround. |
| 1,200-reader issue | Choose Kit if the whole issue must arrive the same day. Record the exact plan, observed result and any workaround. |
| 180 updates plus 40 welcomes | Exact automation availability remains a separate question. Record the exact plan, observed result and any workaround. |
| Growth constraint | Price the first constraint your workload will reach. Record the exact plan, observed result and any workaround. |

If both products pass
Compare the total cost for the same workload, then the effort to move your files and train the next user. Keep a working setup when neither alternative solves a concrete problem. If neither passes, return to the software finder with the missing requirement.
Before purchasing in Europe
Check availability in your country, invoice currency and applicable VAT, renewal and cancellation terms, supported languages and support hours. For uploaded business data, review the provider's processing terms and export/deletion options. These are checks to make, not a claim that either provider meets every requirement.

The key difference in the free allowances
Kit publishes a free allowance of up to 10,000 subscribers with unlimited email broadcasts. Brevo publishes storage for 100,000 contacts with a limit of 300 sends per day. A broadcast is a campaign sent to an audience; it is not a guarantee of unlimited automated workflows. Check the current official sources below before choosing.
A newsletter to 1,200 readers
If all 1,200 readers should receive the same issue on Tuesday, a daily cap of 300 does not fit the brief. Dividing 1,200 by 300 gives four sending days at full capacity, before other messages. Kit’s published broadcast allowance is the more relevant starting point for this scenario. You still need to check its content rules, account approval and the features your newsletter depends on.
A small customer update
If you have 180 customers and send one update on a given day, that campaign uses 180 sends. Adding 40 welcome messages brings the day to 220. In that scenario, Brevo’s published daily cap leaves some room. The practical question becomes whether your forms, contact fields and message templates are convenient enough for the person doing the work. We have not tested those workflows ourselves.
Broadcasts and automation deserve separate checks
A weekly newsletter and a sequence triggered by a purchase are different requirements. Sketch the exact sequence you need: what starts it, which fields it checks, what it sends and when it stops. Then check the relevant plan. Do not infer advanced automation capability from the word unlimited beside broadcasts.
Compare the upgrade you would actually buy
Imagine the first constraint you are likely to hit: a campaign deadline, a bigger audience, another editor or an integration. Get a quote for the plan that removes that constraint. Compare the complete billing term, not just the monthly equivalent of an annual payment. We do not publish a universal cheapest winner because the required plan varies with the workflow.
A migration checklist
Before exporting a live list, identify which fields record consent, subscription status and suppression. Check that the destination can preserve their meaning. Build a test segment with your own addresses, verify the signup and unsubscribe paths, and compare the exported fields before moving real subscribers. Avoid sending from both systems during the transition by accident.
Our decision
Investigate Kit first for a larger newsletter that must reach its audience together within a free subscription allowance. Investigate Brevo for smaller daily batches where the contact database and campaign size are different. Use a trial to resolve editor, integration and support questions; our calculations establish capacity constraints, not usability or delivery quality.
