OnVoard Marketing Platform
Stores who want the send question closed for good rather than metered plan to plan.
At the workload above$35/moMarketing Platform, estimated at 10,000 contacts and 20,000 sends/mo
Most comparison pages lead with starting prices. This one compares the same contacts and sends through each vendor’s own pricing rules, and includes a dedicated look at the genuinely free options, since that is usually the real question.
Mailchimp pricing checked September 7, 2026. Mailchimp sets its own prices and can change them any time.
100,000 sends included, fixed to this bracket.
$15/mo for the contacts, plus about $20 for the email at this volume.
Both sides resolved at the same contacts and the same sends, both at list price. Want every OnVoard app rather than email alone? All-In-One runs about $59.80/mo here.
1 line per vendor, every point resolved by the same pricing engine the calculator below runs. Switch a vendor off in the legend to read 2 of them against each other.
The dotted line marks 10,000 contacts, and each price beside a vendor above is that vendor at that point. Lines show the monthly list price at 2 emails per contact a month. A line that stops has run past that vendor’s own published ladder; nothing here is extrapolated. Move the calculator further down the page and the marked position moves with it.
Best for, how each prices, the price at the workload above, key limits, the strongest real reason to pick it, and 1 honest limitation.
Stores who want the send question closed for good rather than metered plan to plan.
Ecommerce brands that want deep segmentation and native SMS, and can afford to skip the free tier once the list grows.
Stores that want native SMS and email in 1 product and will read the promo price as a promo.
The tightest budget among the vendors checked here, with automation still included.
Every free plan in this comparison, with its 2 published limits and the one that runs out first. Free here means a real $0 plan, not a trial.
| Free plan | Contacts | Emails a month | What runs out first |
|---|---|---|---|
| Mailchimp | 250 | 500 | Sending, at 2 emails per contact a month. |
| Klaviyo | 250 | 500 | Sending, at 2 emails per contact a month. |
| Omnisend | 250 | 500 | Sending, at 2 emails per contact a month. |
| MailerLite | 250 | 2,500 | Sending, at 10 emails per contact a month. |
| OnVoard | No limit | 500 | Sending. No contact limit, so 500 emails a month is the only ceiling. |
Contacts and emails are each vendor’s own published free-plan limits. “What runs out first” is the two of them divided, nothing else: a free plan at its full contact ceiling buys that many emails per contact a month before it stops. OnVoard’s free plan is the shape that differs: no contact limit at all, and 500 email sends a month. Past that, the entry cost is 1 $15 contact block plus whatever send setting covers your volume.
Contacts and sends feed the same resolver that priced the card above, live, for every vendor with verified data.
The buttons above fill this in from your contact count. 4x means 4 emails a month per contact.
We use the audience number entered above as the billable contact, profile or subscriber count for each platform. Vendors define billable audiences differently, and a real count after migration can differ.

Pricing is not feature equivalence. These estimates show what each platform charges for the workload you entered. Plans can include different automation, segmentation, SMS, support, ecommerce, and other features.

Centred on the 10,000-contact tier used above; expand for the rest. Every row is independently verified in USD.
Klaviyo, Omnisend and MailerLite each publish a real free plan at 250 contacts, the same shape as Mailchimp's own free tier. Klaviyo and Omnisend cover 500 emails a month; MailerLite covers 2,500. OnVoard's own free plan works the other way round: no limit on contacts, 500 email sends a month. The free-plan table above compares all 5 side by side.
At a small store's workload (500 contacts, 2,000 sends/mo), Mailchimp Essentials prices at $11.75/mo and MailerLite Comfort at $12.00/mo. The gap between them moves with list size, and changes direction more than once, which is why the calculator on this page recomputes rather than naming 1 fixed winner.
Price is the only argument this page makes. If Mailchimp's automation, deliverability, or the fact it also runs your landing pages and social ads is working for you, there is no case here for switching.
Every vendor's ladder was read directly off its own public pricing page (see Sources below) and independently verified row by row, with USD explicitly selected where a vendor's page defaults to another currency. Mailchimp's data was checked September 7, 2026.
