MailerSend
Transactional email, domains, and delivery analytics from a MailerSend account
Overview
What MailerSend does
MailerSend is a transactional email provider, covering the messages an application sends automatically: receipts, password resets, notifications. The connector addresses the account rather than a single function. Sending includes HTML and plain text bodies, copied recipients, attachments and template-driven messages, with scheduled sends that can later be listed, inspected or cancelled. Domain work covers adding a sending domain, retrieving the DNS records it needs, triggering verification and changing settings. Analytics break delivery and engagement down by date, country and recipient client, alongside per-message history for opens, clicks, bounces and complaints. Address verification runs singly or against bulk lists, and webhooks can be created and edited to push events into other systems. Sign-in is an OAuth flow scoped to one MailerSend account.
Tool surface
A 401 answers tools/list, so the 38 tools in the listing remain the publisher's own count rather than anything observed from outside an account.
Availability
Where MailerSend is listed
MailerSend is listed in the Claude connectors directory only. MailerSend has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one.
Claude listing
In the Claude connectors directory
MailerSend publishes 38 tools to Claude, deeper than 86.2% of the 1,253 Claude-listed connectors.
The median Claude-listed connector filed under Productivity publishes 12, so this one runs 26 tools above its bucket's median and ranks 65th of 462 by tool count.
It falls in the 21-50 tools band, which holds 20% of the Claude directory.
MailerSend publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally.
Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there.

MailerSend is community-listed in the Claude directory, the tier 770 of 1,253 connectors sit in (61.5%). It is the default for a self-published server, and says nothing either way about quality.
In the publisher's words
How MailerSend describes it
The MailerSend connector lets Claude work directly with your MailerSend account so you can handle transactional email without leaving the conversation. Send email: Compose and send transactional emails — including HTML, plain text, CC/BCC, attachments, and template-based messages. Schedule messages for later, and list, inspect, or cancel scheduled sends. Domains: Add and configure sending domains, retrieve DNS records, trigger and check domain verification, and update domain settings. Templates: Browse, inspect, and delete email templates in your account. Analytics & activity: Pull delivery and engagement analytics broken down by date, country, and recipient client (user agent name and type). Review message history and recipient activity such as opens, clicks, bounces, and complaints. Email verification: Verify individual email addresses (synchronously or asynchronously) and run bulk verification lists to keep your sending lists clean. Webhooks: Create, list, inspect, update, and delete webhooks to wire MailerSend events into your own systems. Access is scoped to your own MailerSend account through a secure OAuth sign-in — the connector never sees or stores your API key. Just connect, authorize, and start managing your email in natural language.
