Nitrosend is the better choice than Amazon SES overall, with 86 out of 100 against Amazon SES's 65.5. It wins five of the seven tests: working from your AI assistant, receipts and newsletters on one plan, emails in your brand without a designer, the free plan and developer tools. Amazon SES is sending infrastructure. It delivers what a developer's code hands it, and everything above that, from templates to campaigns to the account setup itself, is left to the team. Nitrosend is the email platform your AI assistant can run. To send email from an AI agent with it, add the hosted MCP server at api.nitrosend.com/mcp to Claude, ChatGPT, Cursor or Codex, sign in with OAuth, and ask for the email. It writes and sends the welcome series and the newsletter as well as the receipt. On price both score full marks at 20,000 and 1,000,000 emails a month, though SES is cheaper on sending alone.
Nitrosend vs Amazon SES, compared
The quick version: seven yes-or-no questions a team usually asks when choosing between the two. A tick means the product does it as described on its own pages today. A dash means the honest answer is not a yes or a no.
Nitrosend and Amazon SES, side by side
Checked October 1, 2026| Question | Nitrosend | Amazon SES |
|---|---|---|
| Send from the chatCan an agent send a transactional email without anyone opening the web app? | Yes. Yes, through the MCP server. A single transactional email sends on the call; campaigns and flows stay drafts until approved. | Not a yes or no. Only through a sample or general AWS MCP server, with AWS credentials a person sets up. |
| Hosted MCP serverCan a chat app connect over the web, with no local install? | Yes. Yes. A remote server at api.nitrosend.com/mcp, with OAuth sign-in. | No. No hosted SES MCP server. |
| Sign up with no personCan an agent create the account and send a first email with no DNS work? | Yes. Yes. Signup is an API call, and each brand gets a ready sender on a Nitrosend subdomain. | No. No. A person opens the AWS account, verifies a domain and requests production access. |
| Campaigns and flows in the same planDo newsletters and automations come with the transactional plan? | Yes. Yes, on every plan including Free. | No. No. SES sends, and the campaigns and flows are yours to build. |
| Perpetual free planIs there a free plan that does not run out? | Yes. Yes. 8,000 emails up front, then 500 a month. | No. No. Up to $200 in AWS credits for new customers. |
| Brand learned from your siteDoes it pick up your logo, colors, fonts and voice without a designer? | Yes. Yes. Brand Kit scans your site, and AI Memory keeps house style. | No. No. Templates are HTML you write. |
| Inbound emailCan it receive and parse email sent to your domain? | Not a yes or no. In beta. An agent inbox on your own domain, enabled by request. | Yes. Yes. SES receives mail through receipt rules and Mail Manager. |
Nitrosend meets 6 of 6 yes-or-no questions on this page, Amazon SES 1 of 6. Rows marked with a dash are not a yes or no question for that product.

The verdict in short
Nitrosend is the better choice overall, 86 to 65.5, and it is clearly ahead for a team that runs email from an AI assistant or wants receipts and newsletters on one bill.
Amazon SES does jobs Nitrosend does not, and for a team with engineers to spare they matter. George Hartley, Nitrosend's co-founder, sees the value in the layer above the pipe. On SaaS Stories in September 2026 he said "there's going to be a bunch of kind of dumb email pipes that these agents will just sit on top of." On The Breakout CEO in August 2026 he put Nitrosend's aim as "let's build the best smart pipes for them to kind of communicate." SES is the pipe; the score gap is the layer above it.
Amazon SES is only better on one test. Track record and support, 9 to 4, because it has run at Amazon scale since its launch in January 2011, with deliverability tooling to match. On price the two tie at 10, because both come in under the site's top price band at 20,000 and at 1,000,000 emails a month, and SES is still the cheaper bill for sending alone.

How we scored
Each test is a question with one answer per product, checked against that product's own pages and independent review sites on October 1, 2026. A 10 means the product does the job fully on its standard plans. A 5 means it does part of it, or does it only on a higher plan or in a second product. Amazon SES prices are list prices in US dollars read on its own pricing page at 20,000 and 1,000,000 emails a month, for both the Essentials plan that new accounts start on and the à la carte rate.
Works from your AI assistant, 25 of 100. Can an agent inside Claude, ChatGPT, Cursor or Codex go from nothing to a delivered transactional email, and then read back what happened to it, with no person opening the web app along the way? Scored on the first-party MCP server and what its tools cover, a CLI that works in a non-interactive runner, account and sender setup over the API, and listings in the chat apps people already work in. Scored on one written rule for every vendor: a first-party server the vendor runs and that can send counts fully; a third-party wrapper (Zapier, Composio, Kanopi, community servers) counts for less; a server that only drafts or reads counts for less than one that sends.
Receipts and newsletters on one plan, 15 of 100. Can receipts and password resets, and the newsletters and automated flows that follow them, go out from one account, on one bill, through one API, with the two streams kept apart?
Emails in your brand, no designer, 10 of 100. Does the product produce the receipt, reset and welcome emails in your brand's own logo, colors, fonts and voice, or does a developer have to write or buy the HTML template first?
Free plan, 10 of 100. How far can a developer get on the free plan before paying: the monthly volume, the daily ceiling, any one-off starter allowance, and whether the plan is perpetual or a trial that ends.
Price, 15 of 100. What does sending cost at 20,000 emails a month, where most teams start, and at 1,000,000, where a busy product ends up? Scored on list prices in US dollars, paid monthly, at the cheapest plan that covers the volume. Every ranking on this site uses the same fixed scale. At 20,000 emails, $20 or less scores 10, then $25 scores 9, $32 scores 8, $40 scores 7, $50 scores 6, $70 scores 5, $100 scores 4 and $140 scores 3. At 1,000,000, $500 or less scores 10, then $625, $800, $1,000, $1,250, $1,750, $2,500 and $3,500 step down the same way. Anything dearer, or a price given only by quote, scores 2. The score is the average of the two.
Developer tools, 15 of 100. How complete is what a developer builds on: a REST API with an OpenAPI spec, official SDKs across languages, a CLI, an SMTP relay, documented delivery-event webhooks, idempotent sends, a test or sandbox mode, inbound email handling, and how deep the reference docs go?
Track record and support, 10 of 100. How long has it run transactional sending at scale, which deliverability controls can you own (dedicated IPs, suppression, separate streams, a published uptime SLA), and what support comes with the plan?
What each one costs in 2026
Amazon SES pricing now has two structures. À la carte is $0.10 per 1,000 emails with no minimum. The Essentials plan is $0.16 per 1,000 up to 10 million a month and bundles deliverability features, and new SES accounts have started on Essentials since July 21, 2026, though they can switch to à la carte at any time. Attachment data costs $0.12 per GB on top. There is no standing free plan. New AWS customers get up to $200 in AWS Free Tier credits that can be spent on SES.
Nitrosend's pricing is $20 for 20,000 emails on Pro and $500 for a million on Enterprise. Transactional, campaigns and flows draw on the same allowance, and contacts are unlimited.
At 20,000 emails a month, where most teams start, SES is $3.20 on Essentials and Nitrosend is $20. At a million, SES is $160 on Essentials and Nitrosend is $500. On sending alone SES is far cheaper at both volumes, and both score full marks on the site's price scale.
What sending costs at two volumes
List prices, USD, October 1, 2026| Scenario | Nitrosend | Amazon SES |
|---|---|---|
| 20,000 emails a month | Pro, $20 a month | $3.20 on Essentials, or $2 à la carte |
| 1,000,000 emails a month | Enterprise, $500 a month | $160 on Essentials, or $100 à la carte |
| Add newsletters and a welcome series | Counted in the same allowance, contacts unlimited | No campaign builder or flows. Build them yourself or add another tool |
The two are not priced for the same job. An SES bill covers delivery. A Nitrosend bill covers delivery plus the agent, the templates, the campaigns and the flows. On Pro and above Nitrosend accepts your own sending keys, SES included, so a team can keep SES as the delivery layer and pay AWS directly. A team with engineers to spare can run SES on its own and build the layer above it. Add the cost of building and running that layer, the templates, the campaign tools and the event handling, to the SES bill before you compare the two.
Where Amazon SES is the better pick
Amazon SES scores higher on one of the seven tests and ties on price, and it does a few jobs Nitrosend does not. For a team with engineers to spare those matter. Read these before you choose Nitrosend.
- Pick Amazon SES if the per-email price decides it. A million emails cost $100 à la carte or $160 on Essentials, against $500 on Nitrosend Enterprise. Both score 10 on the site's price scale, but SES is the smaller bill for sending alone.
- Pick Amazon SES if your system needs SMTP, inbound email or deep AWS plumbing. It has AWS SDKs in several languages, an SMTP interface, event publishing to the rest of AWS, inbound receiving through receipt rules and Mail Manager, and a mailbox simulator for testing bounces and complaints. Nitrosend's SDK is Node and TypeScript, and other languages call its REST API. It has no SMTP relay, and it receives email only through an agent inbox that is still in beta.
- Pick Amazon SES if you want the longest track record and the deepest controls. It scores 9 to 4. SES has run since 2011 and carries managed dedicated IPs, Virtual Deliverability Manager and tenant isolation. Nitrosend runs its own managed sending on SES.
The gap is everything a person has to do before the first email. A new account starts in the SES sandbox, limited to verified addresses and 200 messages a day, until a person requests production access. There is no SES-specific MCP product. AWS publishes a sample SES MCP server you build from source with Java, and its managed, general-purpose AWS MCP Server runs AWS API calls, SES included, on IAM credentials a person sets up.
The same gap shows after the send. SES reports a bounce, a complaint or a delivery only once someone creates a configuration set and an event destination in CloudWatch, Data Firehose, EventBridge, SNS or Pinpoint, and then writes the code that reads it. Until then a password reset that bounced looks the same as one that arrived. Nitrosend posts a signed event for each transactional email to your HTTPS endpoint when it is delivered, bounced, complained about or fails for good, in the Standard Webhooks format any stock library can verify.
On Nitrosend the agent starts from nothing: an account created with one API call, a ready sender on a Nitrosend subdomain, a first send, and then campaigns and flows from the same MCP server. The whole email stack runs from inside the assistant. A transactional email goes out on the call, and a campaign or flow waits as a draft until someone approves it.
Moving from Amazon SES to Nitrosend
Most teams on SES should not move delivery at all. They should put Nitrosend on top of it.
- Keep SES underneath. On Pro and above, connect your SES credentials as the sending provider. Delivery and the per-email bill stay on your AWS account, and the agent, templates, flows and newsletters run in Nitrosend.
- Stop hand-coding templates. SES templates are HTML you write and store. Nitrosend's Brand Kit reads your site and every email it drafts uses the logo, colors and fonts it found, with no template file to maintain. The transactional template guide covers what each receipt and reset needs.
- Own the bounce domain. By default SES sends with a MAIL FROM domain under amazonses.com. SPF passes, but for Amazon's domain, not yours, so DMARC can pass only through DKIM until a custom MAIL FROM subdomain is set up with its own MX and SPF records. Nitrosend's domain setup lists a return-path record next to SPF and DKIM, so check that it is in place before the first send.
- Keep the streams apart. Nitrosend sends transactional and marketing mail on separate streams, so a password reset never queues behind a newsletter. The difference between transactional and marketing email is the background.
- Plan around the gaps. If your system relies on SES inbound receiving, SMTP or deep AWS event plumbing, keep that part in AWS, and plan the receipt rules early: SES allows 200 rules per rule set, a limit AWS does not raise, and only one rule set is active at a time, so one rule per customer domain stops at 200 domains. Nitrosend's agent inbox, which receives mail on your own domain, is in beta and enabled by request.
Which one to pick
Pick Nitrosend if an agent should set up, write, design and send the email from the assistant the team already uses, the team also needs a welcome series and a newsletter, or nobody wants to build templates and campaign tooling around a raw sending API. It scores higher overall, 86 to 65.5. Teams that want both can keep SES for delivery and run Nitrosend on top. The Nitrosend MCP server and the ChatGPT app are the two ways most teams start, and transactional email is the primer on what belongs in which stream.
Pick Amazon SES if you have engineers who will build and own the sending layer, the volume is large enough that the per-email price decides it, and you already live in AWS. Nothing is cheaper to send through, and nothing gives a developer more control.
Nitrosend vs Amazon SES FAQ
$0.10 per 1,000 emails à la carte, or $0.16 per 1,000 on the Essentials plan, which new SES accounts have started on since July 21, 2026, according to AWS's SES pricing page. Attachment data is $0.12 per GB on top. 20,000 emails a month is $3.20 on Essentials, and a million is $100 à la carte or $160 on Essentials.
Not a standing one. New AWS customers get up to $200 in AWS Free Tier credits that can be spent on SES. Nitrosend's Free plan gives 8,000 emails up front and then 500 every month, with no expiry and no credit card.
No. On sending alone SES is far cheaper, $3.20 against $20 at 20,000 emails a month and $160 against $500 at a million. Nitrosend's price also covers the agent, templates, campaigns and flows, and on Pro and above you can plug your own SES account in and keep paying AWS for delivery.
Not one built for SES. AWS publishes a sample SES MCP server you build from source, and its managed AWS MCP Server can call SES among every other AWS API. Both run on AWS credentials a person sets up. Nitrosend's MCP server is hosted, signs in with OAuth, and covers campaigns, flows, contacts and domains as well as sends.
Add the hosted MCP server at api.nitrosend.com/mcp in Claude (or ChatGPT, Cursor or Codex) and sign in with OAuth when the window opens. Point Brand Kit at your site so emails come out in your logo, colors and fonts. Then ask for the email in plain words: a transactional message goes out on the call, and a campaign or flow is saved as a draft until you approve it. The MCP server page has the setup for each assistant.
It can deliver bulk mail and manage contact lists and unsubscribes, but it has no campaign builder, segment editor or automation flows. Those are yours to build or buy. Nitrosend includes them on every plan.
This review does not score it, because neither product publishes a comparable inbox-placement number. Whichever you use, reputation belongs to the sending domain, so authenticate it and keep transactional and marketing mail on separate streams.
