2,500 subscribers, two campaigns a year: monthly plan or prepaid credits?
This is a worked buyer scenario, not a claim about average customer usage. Assume 2,500 opted-in recipients and two campaigns, with one email per recipient per campaign. That is 2,500 × 2 = 5,000 recipient sends per year before tests, resends, welcome emails or other automations. The relevant constraint is also the largest single campaign, not only the annual total.
Check storage, campaign-day capacity and automation separately
A large contact allowance does not mean a large same-day sending allowance. Brevo’s free plan documents 300 daily sends. At that ceiling, 2,500 ÷ 300 requires at least nine days, assuming no other emails consume the allowance. That is not suitable for a time-sensitive one-day announcement.
Brevo’s entry Starter tier combines 5,000 monthly sends with storage for up to 500 contacts; higher tiers change both limits. Do not read the headline sending allowance as permission to store a 2,500-person list on that entry tier.

Credits can fit occasional sending, but expiry changes the calculation
Mailchimp’s Pay As You Go credits expire 12 months after purchase. Brevo documents prepaid email credits that do not expire. These are different from a monthly subscription’s recurring allowance; unused monthly sends should not be assumed to roll over.
Compare the live price of the smallest credit pack that covers the required campaign, its contact and feature constraints, and how much would remain unused. Buying a very large pack is not automatically cheaper when most of it will expire or never be used. Neither product is declared the cheapest without a current, like-for-like quote.

A free plan can be useful without fitting this list
MailerLite changed its free plan on June 16, 2026: 250 active subscribers and 2,500 monthly emails. A 2,500-email allowance is not a 2,500-subscriber allowance. Use the free tier for a genuinely small list or a limited evaluation, not as the assumed solution for this worked scenario.
Review the bill before migrating the whole audience
Mailchimp states that archived contacts do not count toward the billing tier. Archiving retains their data but removes them from the active contact table; it is different from permanent deletion. Check audience duplicates and inactive records before deciding that migration is the only way to reduce the bill.
Keep unsubscribe and suppression status intact. Cost reduction is not a reason to re-import an opted-out contact as subscribed. A data-erasure request is a separate issue from routine list cleanup. Review the vendor’s instructions before applying bulk changes.
Choose by the pattern you can actually predict
For one or two isolated announcements, compare prepaid sending first, subject to storage and campaign-day constraints. For a regular newsletter plus welcome and follow-up sequences, price a recurring plan against peak-month volume. For ecommerce, add the exact store events and revenue reporting required rather than choosing only by contact price.
Treat a change of provider as a small migration project: export consent and suppression records, recreate the essential form and template, check domain setup, and test a permitted small sample. The proposed workflow does not guarantee inbox placement or campaign results.
| Decision input | Calculation | What it establishes |
|---|---|---|
| Annual recipient sends | 2,500 × 2 = 5,000 | Baseline only; excludes tests and automations |
| Largest one-day campaign | 2,500 recipients | Check burst capacity, not just an annual average |
| 300-send daily ceiling | ceil(2,500 ÷ 300) = 9 days | Not a same-day campaign solution |
| Recurring-plan comparison | 12 × monthly quote | Compare required features, contacts and peak sends |
| Prepaid comparison | Pack price + required add-ons | Include expiry, unused credits and storage limits |
No credit-pack price or savings percentage is invented. A cheaper total is actionable only when the selected plan can store the list, send the campaign on time, and run the required features.
Before you choose: a buyer-run acceptance checklist
- Count eligible active contacts and preserve unsubscribe/suppression status.
- Record the largest campaign day and include transactional or automation emails where they share limits.
- Check contact storage, same-day sending, feature access and account-user allowances on the proposed plan.
- Record credit expiry and monthly rollover rules separately.
- Compare current annual total costs in the same currency with the same required features.
- Keep the existing provider until a controlled migration check passes; do not delete the source audience merely to test an alternative.
