Total cost of ownership
3-year cost across three real scenarios
Brevo is a cloud subscription billed monthly on send volume per its published Free / Starter / Business / Enterprise tiers; AcelleMail is a one-time license you self-host on a VPS plus a sending service. The dollar values below assume Amazon SES at $0.10 per 1,000 emails for the AcelleMail rows. Specific Brevo tier prices change — consult brevo.com/pricing for current values.
Small business — 1,000 contacts, 4× sends/month
Brevo — Brevo Free or entry-tier paid plan
Brevo Free tier covers a published daily-send cap. 4,000 monthly sends across 1,000 contacts may fit Free or require an entry paid tier — verify against current brevo.com/pricing thresholds.
Recurring monthly subscription if above Free; check current paid-tier cost.
AcelleMail — AcelleMail Regular License + small VPS + Amazon SES
$5/mo VPS + $0.40/mo SES (4,000 sends × $0.0001)
$74 license + $180 VPS + $14 SES = $268 total
At 1,000 contacts and 4 sends/month, both models are inexpensive. AcelleMail one-time cost is ~$268 over 3 years; Brevo at this volume may fit Free. Compare against your current Brevo invoice on the published tier.
Growing newsletter — 10,000 contacts, 80,000 sends/month
Brevo — Brevo Business or higher tier covering 80K monthly sends
Brevo paid tier billed monthly per the published send-volume tier covering 80K monthly sends. Marketing automation is included on the Business tier per brevo.com/pricing.
Recurring monthly subscription × 36 months — verify against current pricing.
AcelleMail — AcelleMail Regular License + $10 VPS + Amazon SES
$10/mo VPS + $8/mo SES (80,000 × $0.0001)
$74 license + $360 VPS + $288 SES = $722 total
At 10K contacts and 80K monthly sends, AcelleMail self-hosted on SES converges to roughly $20/month after the license is amortized. The cost gap depends on the Brevo tier covering this volume.
Agency / SaaS — 50,000 contacts, 400,000 sends/month, 50 client tenants
Brevo — Brevo + custom multi-tenant integration layer
Brevo is a single-account product per subscription; agencies typically operate 50 separate Brevo accounts or a custom routing layer over a single Brevo subscription.
50 accounts × subscription, OR aggregate Brevo Business/Enterprise + custom tenant build.
AcelleMail — AcelleMail Extended License + $20 VPS + Amazon SES (multi-tenant on a single instance)
$20/mo VPS + $40/mo SES (400,000 × $0.0001) — covers all 50 tenants on one install.
$199 license + $720 VPS + $1,440 SES = $2,359 total
AcelleMail Extended ships a multi-tenant SaaS layer (customer accounts, plans, 6 payment gateways, dunning) bundled. Brevo handles the cloud infrastructure but does not bundle reseller-billing primitives.
