The pricing philosophy is the product
SendX and Mailchimp both charge by how many contacts you store. Where they differ is what that price unlocks.
SendX has one plan. Pick your contact count, and you get unlimited sends, automations, A/B testing, full API access and 24/7 chat and email support. There is nothing to upgrade to except more contacts or the optional Elevated Support add-on.
Mailchimp has four tiers. Free and Essentials cover campaigns and basic automation. Standard adds customer journeys, send-time optimization and more testing. Premium adds advanced segmentation, multivariate testing and phone support. Each tier also comes with a monthly send cap relative to your contact count.
That difference shapes the whole comparison.
What 10,000 contacts costs
| SendX | Mailchimp | |
|---|---|---|
| Monthly billing | About $49.99 | About $110 (Essentials), $135 (Standard), $350 (Premium) |
| Annual billing | $37.49/month (25% off) | Occasional promotions |
| Sends | Unlimited | Capped by tier |
| Automations | Included | Journeys from Standard |
| A/B testing | Included | Paid plans; multivariate on Premium |
| Support | 24/7 chat and email | Email and chat; phone on Premium |
| Free option | 14-day trial, 60-day money-back guarantee | Free plan: 250 contacts, 500 sends |
For a business that sends campaigns and runs a few automations, SendX costs roughly a third to half as much at 10,000 contacts. Mailchimp also counts unsubscribed contacts, so an older list can sit in a higher tier than its active size suggests.
Where the money goes with Mailchimp
Paying more for Mailchimp makes sense if you use what SendX lacks:
- A website builder and stronger landing pages. Useful if you do not already have a site.
- Social posting, ad campaigns and postcards managed from the same account.
- 300+ integrations. If your CRM, store or event tool connects natively to Mailchimp but not SendX, that can outweigh the price gap.
- A free plan for a list under 250 contacts.
- A larger template library and a polished editor.
If none of those matter, most of the extra spend buys familiarity.
Where SendX is stronger
- No tier decisions. Automations and A/B testing are there from day one.
- Unlimited sends. Send daily if your audience wants it without watching a cap.
- Support on the base plan. 24/7 chat and email is included; Mailchimp reserves phone support for Premium.
- Guarantee. A 60-day money-back guarantee, with conditions, lowers the risk of trying it.
The trade-offs are a smaller template library, a smaller integration directory (Zapier and the API fill gaps), basic landing pages and no permanent free plan. Hands-on deliverability and campaign help costs $225/month through Elevated Support.
Before switching, check two things in your current Mailchimp account: which integrations send data into it, and which landing pages or forms are hosted there. Those are the pieces that take the longest to replace, and they decide whether SendX's lower price turns into real savings or a week of rework.
Support as part of the price
The two tools treat support very differently, and it matters most in your first months or during a deliverability problem.
SendX includes 24/7 live chat and email support on every paid plan. If you want hands-on help, such as expert calls, warm-up strategy, campaign setup and issue monitoring, its Elevated Support add-on costs $225/month. That add-on alone costs more than the base plan at 10,000 contacts, so it is aimed at teams that want a partner rather than a help desk.
Mailchimp's support scales with the tier. Free users get limited help, paid plans add email and chat, and phone support is reserved for Premium, which is about $350/month at 10,000 contacts. For a small team that expects to ask questions often, SendX's included chat is a meaningful difference.
Trial and guarantee versus a free plan
SendX has no permanent free plan. Instead it offers a 14-day trial without a credit card and a 60-day money-back guarantee with conditions. Mailchimp lets you stay on a free plan indefinitely, but only up to 250 contacts and 500 sends a month.
For a list under 250 contacts that sends rarely, Mailchimp's free plan is hard to beat. Once you pass that, you are paying either way, and SendX's lower price and guarantee reduce the cost of trying it.
How the tiers play out over a year
Picture a business at 10,000 contacts that starts with a newsletter and, six months later, wants a welcome series with branches and a re-engagement flow.
On Mailchimp, the newsletter runs fine on Essentials at about $110/month. When the team wants multi-step journeys with branching, it needs Standard at about $135/month. If it later wants advanced segmentation or multivariate testing, that means Premium at about $350/month. Each step is a plan decision, and send caps rise with each tier.
On SendX, the account costs about $49.99/month (or $37.49 annually) the whole time. The welcome series, re-engagement flow and A/B tests are already included. The only thing that changes the bill is list growth.
For teams that expect their email program to become more sophisticated over time, SendX's single plan avoids a series of upgrade conversations. For teams that will never go beyond a newsletter, Mailchimp Essentials is closer in price, and its free plan covers the very beginning.
Switching from Mailchimp to SendX
- Export the whole audience from Mailchimp, including unsubscribed and cleaned contacts.
- Recreate fields and tags in SendX for the merge fields and tags you segment on.
- Import subscribed contacts and suppress the unsubscribed and cleaned ones.
- Authenticate your domain with SPF, DKIM and DMARC before sending.
- Rebuild forms and popups and replace Mailchimp-hosted signup forms on your site.
- Rebuild journeys as SendX automations; this is also a good moment to simplify.
- Recreate templates for your newsletter and key automations.
- Check integrations. Replace any native Mailchimp integration with a SendX one, Zapier or the API.
- Send to engaged contacts first, then widen over a few campaigns.
Going from SendX to Mailchimp is the same list work in reverse, plus choosing the Mailchimp tier whose features and send cap fit how you actually send.
Which sender fits which tool
| Situation | Better fit | Why |
|---|---|---|
| Weekly newsletter plus automations at 10,000 contacts | SendX | All features on one plan, about $49.99/month |
| Under 250 contacts, occasional sends | Mailchimp | Free plan covers it |
| Daily or near-daily sends | SendX | Unlimited sends with no tier cap |
| Business needing a website and social scheduling | Mailchimp | Website builder and social tools included |
| Small team that wants chat support at any hour | SendX | 24/7 chat and email on every plan |
| Stack built on a niche integration | Mailchimp | 300+ integrations |
Migration checklist
| Workstream | Mailchimp to SendX | SendX to Mailchimp |
|---|---|---|
| Contacts | Export full audience incl. unsubscribed and cleaned | Export contacts with tags and custom fields |
| Suppressions | Suppress unsubscribed and cleaned addresses | Import unsubscribed contacts as unsubscribed |
| Forms | Rebuild forms and popups, replace embeds on your site | Rebuild forms and replace SendX embeds |
| Automations | Rebuild journeys as automations | Rebuild automations as journeys; check tier requirements |
| Templates | Recreate newsletter and automation templates | Recreate templates in Mailchimp's editor |
| Integrations | Swap native Mailchimp integrations for SendX, Zapier or API | Reconnect integrations natively where available |
| Plan choice | One plan, pick contact tier and billing term | Choose tier by features needed and monthly send cap |
Where Sequenzy fits
SendX and Mailchimp share one assumption: you pay for every contact you store. For a SaaS company whose list is its user base, many of those contacts only receive a few lifecycle emails a month. Sequenzy has unlimited contacts and charges by emails sent, typically $49/month for 60k emails (unlimited subscribers), and triggers sequences from Stripe, Paddle and Polar billing events. It also sends transactional email in the same account.
If you send frequent campaigns to a stable marketing list, SendX's unlimited sends may be cheaper than any send-priced tool. Sequenzy also does not have Mailchimp's website builder or social tools.
Decision checklist
- Do you want every email feature without choosing a tier? SendX.
- Do you send more than once a week? SendX's unlimited sends avoid Mailchimp's caps.
- Is your list under 250 contacts? Mailchimp's free plan may be enough.
- Do you need a website, social scheduling or a specific integration? Mailchimp.
- Is your list a SaaS user base with billing-triggered flows? Compare a send-priced SaaS tool.
