Fits (10)
- Brevo$0.00/mo
Free plan · confidence: exact · Verified 2026-08-18
Caveats (1)
- Free plan caps: 300 emails/day (~9,000/month if sending daily), up to 100,000 contacts stored, marketing automation limited to 2,000 contacts, 1 user seat, Brevo branding on emails.
- Kit$0.00/mo
Newsletter plan · confidence: exact · Verified 2026-08-18
Caveats (1)
- Free plan caps: up to 10,000 subscribers, 1 basic Visual Automation, no A/B testing, SMS, or advanced deliverability reporting.
- Sendy$12.15/mo
Self-hosted (single-domain license) plan · confidence: estimated · Verified 2026-08-18
Caveats (5)
- License is actually a one-time $69 fee, not a subscription — amortized over 12 months here purely so the total is comparable to subscription vendors' monthly cost.
- Hosting cost is a modelling assumption (entry-level VPS), not a Sendy fee — actual infrastructure cost depends entirely on the operator's chosen host and traffic.
- Excludes optional paid add-ons: installation service ($79), AI assistant bundle ($39).
- Excludes possible major-version upgrade fees, charged at a fraction of the original license cost.
- Contact list size does not affect Sendy's own price — cost scales with emails sent, not contacts stored.
- Mailgun$15.00/mo
Basic plan · confidence: exact · Verified 2026-08-18
Caveats (4)
- Contact list size does not affect Mailgun's price — plans are tiered by monthly email send volume.
- Excludes separately priced Mailgun add-on products: Optimize (advanced deliverability), Validate (email verification beyond any plan-included allotment), and Inspect.
- Enterprise-scale volume (beyond Scale's 100,000/mo allowance, or requiring SLA/custom terms) is quote-only and not priced here.
- A legacy "Flex" pay-as-you-go plan may or may not still be offered — Mailgun's own help center describes it as a deprecated/legacy plan while some third-party sources describe a still-active $2/1,000-email rate. This could not be resolved from a first-party source and is not modelled.
- Postmark$15.00/mo
Basic plan · confidence: exact · Verified 2026-08-18
Caveats (3)
- Postmark does not currently offer annual billing — the same monthly price applies regardless of usage.billing (confirmed at postmarkapp.com/pricing, 2026-08-18).
- Contact count does not affect Postmark pricing — Postmark stores no contact/audience list; only email volume drives cost.
- Excludes the optional Custom Activity Retention add-on (from $5/mo) and possible custom/enterprise pricing for very high-volume senders, which Postmark handles via a sales conversation rather than published rates.
- SendGrid$15.00/mo
Basic plan · confidence: estimated · Verified 2026-08-18
Caveats (4)
- Basic's $15/mo entry-tier price is confirmed as the plan's "starting at" headline price, but its pairing with 5,000 contacts is triangulated from third-party sources, not read directly off sendgrid's own rendered page.
- SendGrid also sells a separate Email API product (send-volume-tiered, billed independently from Marketing Campaigns): Essentials from $19.95/mo, Pro from $89.95/mo (includes 1 dedicated IP), Premier custom-priced. Not included in this estimate — see twilio.com/en-us/products/email-api/pricing.
- SendGrid does not offer annual/prepay billing on standard self-serve plans — all figures here are monthly.
- Contact-tier prices above each plan's lowest ("starting at") tier are not published as static, verifiable text (the pricing page uses a client-side slider) and are excluded rather than estimated with false precision.
- ActiveCampaign$19.00/mo
Starter plan · confidence: exact · Verified 2026-08-18
Caveats (4)
- Excludes paid add-ons: Postmark transactional email/SMTP relay, SMS credits, and the Pipelines CRM / Sales Engagement bundle.
- Excludes extra user seats beyond each plan's included count (Starter 1, Plus 1, Pro 3, Enterprise 5) — additional seats are billed per seat.
- Modelled contact tiers go up to 25,000 (Starter, a real vendor-enforced cap) and 100,000 (Plus/Pro/Enterprise, a modelling cutoff — ActiveCampaign's own pricing data extends further via a contact-sales path not modelled here).
- Annual billing is one upfront annual charge, not a monthly instalment — the monthly figure shown for annual billing is that annual total divided by 12, for comparison only.
- MailerLite$19.00/mo
Comfort plan · confidence: exact · Verified 2026-08-18
Caveats (3)
- Excludes MailerSend (transactional email, SMTP relay, SMS) — a separate product with its own billing, reached via SSO from a MailerLite account.
- Excludes the Enterprise-only dedicated IP add-on.
- Billing is based on active subscribers within the billing cycle; unsubscribed/bounced contacts do not count.
- Klaviyo$45.00/mo
Email plan · confidence: estimated · Verified 2026-08-18
Caveats (4)
- klaviyo.com/pricing could not be fetched directly during this research pass (the page returned HTTP 404 to automated requests); every price point here is triangulated from multiple independent secondary sources, not confirmed first-party. Confirm the exact current figure at klaviyo.com/pricing before relying on this estimate.
- Excludes add-on products priced separately by their own usage (Customer Hub, Marketing Analytics, Helpdesk, Customer Agent, Advanced KDP, Composer AI credits).
- Mobile Messaging (SMS/MMS/WhatsApp) spend beyond the plan's included dollar pool is billed per-message at rates that vary by channel, country, and number type — not modelled here.
- Email price at 1,500 active profiles is an estimate — confirm the exact current figure at klaviyo.com/pricing.
- Mailchimp$45.00/mo
Essentials plan · confidence: estimated · Verified 2026-08-18
Caveats (4)
- Excludes paid add-ons: transactional email/SMTP relay (Mandrill), SMS, dedicated IP.
- Contact-tier prices above 500 (Essentials/Standard) and 10,000 (Premium) are triangulated from third-party sources, not confirmed directly against mailchimp.com — treat as estimates.
- Billed contacts typically include unsubscribed contacts still present in the audience unless archived or deleted.
- Essentials price at 2,500 contacts is an estimate — confirm the exact figure at mailchimp.com/pricing.
