MailCheap vs SendNeo

MailCheap vs SendNeo

Disclosure: SendNeo is built by Yorker Media, the team behind this blog.

MailCheap and SendNeo both appeal to people who want a simpler publishing stack, but they solve different versions of that problem. MailCheap is a newsletter-first product with an open-source implementation. SendNeo combines a transactional email API with newsletters in one hosted account. The right choice depends on whether your publication is the whole business or one part of a product.

The comparison below uses the verified product information available on 16 October 2026. It is meant to clarify tradeoffs, not declare a universal winner.

What MailCheap does well

MailCheap is newsletters only. That narrow focus can be a strength: a creator can think in campaigns, subscribers, and issues without carrying a transactional API into the decision. MailCheap is also open source under AGPL-3.0, which matters to teams that want to inspect the code, self-host, or make a long-term plan around a public license. Marc Lou’s track record is another reason some makers will prefer the project and its community.

MailCheap offers an MCP server and REST API, so an operator does not have to choose between a dashboard and automation. Its current account limit is up to three newsletters. That can be enough for a single publication or a small portfolio where each newsletter has a clear identity.

MailCheap’s verified pricing is $19 per month for 20,000 emails, $39 for 75,000, $79 for 200,000, $149 for 500,000, and $349 for 2 million. There is no free plan or trial in the verified snapshot. Campaigns stop when the monthly email allowance runs out, and welcome emails are skipped at that point. Those details should be part of a launch plan if the list is active or the welcome sequence is important.

What SendNeo does differently

SendNeo has two lanes in one account. Developers can use a Resend-compatible API at https://sendneo.yorkermedia.com/api; creators and publishers can build audiences, use a hosted sign-up page or embeddable form, write Markdown or HTML broadcasts, test them, schedule them, and publish a public archive.

SendNeo charges for emails sent, never contacts. The Free plan is $0 for 3,000 emails per month with a 100-per-day maximum. Starter is $9 for 30,000, Growth is $19 for 75,000, Pro is $49 for 200,000, Scale is $99 for 500,000, and Business is $199 for 1 million. Yearly billing gives two months free. Paid plans include every feature, and contacts are unlimited on every plan.

The operational difference matters when a product and a publication share an account. If a plan’s monthly emails run out, transactional mail plus welcome and confirmation emails keep going for up to 20% more while you upgrade. Broadcasts wait. This protects a password reset or a new-subscriber confirmation from being caught behind the next campaign.

Side-by-side

The table does not measure implementation quality, community, or personal trust. Those are valid decision factors and require your own evaluation.

When MailCheap is the better pick

Choose MailCheap if your job is only newsletters, you value open source and the option to self-host, and three newsletters cover the publication plan. It can also be a good choice when the project’s community and Marc Lou’s history matter more to you than a transactional API.

An open-source deployment does create ownership work. You are responsible for hosting, upgrades, backups, abuse controls, delivery operations, and the path from a bounce to a suppression. That is not a criticism; it is the cost of control. If you already run that stack, it may be exactly what you want.

When SendNeo is the better pick

Choose SendNeo if your application sends receipts, invitations, or alerts and the same organization also sends newsletters. A single verified domain, account, and bill reduce the number of systems you have to reconcile. The Free and Starter tiers also give a smaller publication a way to begin without paying for contacts or running infrastructure.

SendNeo is especially useful when a welcome email must keep working during a busy month. The critical-mail allowance and automatic suppression controls make the failure mode clearer: broadcasts wait, while essential messages keep going during the upgrade window. New accounts still begin in review, and live sending to outside recipients opens after a quick human review, usually within one business day.

Deliverability and migration questions

Both products need permission-based lists and accurate sender information. Before a move, export your audience, keep the original consent and unsubscribe records, and do not re-add prior unsubscribes. SendNeo’s CSV importer drops invalid, role, disposable, and duplicate addresses and preserves earlier unsubscribes, but an import filter cannot create consent that never existed.

For a SendNeo migration, verify your domain, create a test key, send to the deterministic test addresses, and make a small broadcast. Read Newsletters for forms and archives, and Deliverability for one-click unsubscribe, SPF, DKIM, DMARC, and review mode. For an API integration, Migrate from Resend covers the base URL and endpoint mapping.

The decision

MailCheap is a strong newsletter-only and open-source choice. SendNeo is a strong choice when newsletters and transactional messages need to live together, when contacts should be unlimited, or when critical mail should keep moving during a plan upgrade. Pick the product that matches the system you are actually willing to operate, then test the exact audience, message, and failure modes before launch.

Questions to ask before switching

Ask how each product handles a person who joins, confirms, receives a welcome message, and then unsubscribes. Test an address that bounces and make sure it stays suppressed. Check whether the public archive contains exactly the issues you intend to publish, and whether an export includes tags and names rather than only an email column.

Also decide who owns the sending domain. A self-hosted MailCheap deployment gives you control, but it also means your team must protect the server, rotate credentials, process complaints, and keep the application available. A hosted SendNeo account removes that hosting layer while keeping the DNS and list decisions visible in the dashboard. Neither approach removes the need for a permission record.

A useful comparison is to draft the same issue in both systems, send a test to your own team, schedule it for a future time, and then cancel or edit it. Add a contact through the form and through the API. The small workflow reveals whether the product fits your editorial habits better than a feature list.

The final decision can be revisited as the publication changes. Start with the smallest system that meets the audience and compliance needs, document the export path, and review the sending pattern after a few issues. A clear exit plan is useful whether you choose an open-source deployment or a hosted account.
