Connect Claude & ChatGPT to MailChannels

Ask your AI how many emails bounced this week, whether a domain is set up to send, or to take an address off the suppression list. It can send email through MailChannels, check a domain's DKIM, SPF and Domain Lockdown, create and manage DKIM keys, and read performance, engagement, volume and usage numbers. Sub-accounts and top senders are covered too.

Try asking

“Is example.com set up correctly to send through MailChannels?”
The AI checks the domain's DKIM, SPF and Domain Lockdown setup and reports whether mail from it will be accepted.
“Create a DKIM key for example.com with selector mcdkim.”
It creates the key pair and returns the DNS record you need to publish.
“How many emails were delivered and bounced last week?”
It reads performance metrics for the period: processed, delivered, bounced and dropped.

What your AI can do

Sending and domains

Send email with to, cc and bcc, render it first with a dry run, and check DKIM, SPF and Domain Lockdown for a domain.

DKIM and suppressions

Create, list and activate or revoke DKIM keys, and add or remove recipients on the suppression list.

Metrics and usage

Read performance, engagement, recipient behaviour and volume metrics, account usage, sub-accounts and top senders.

“Why is [email protected] not getting our emails?”
It looks her up in the suppression list and shows the source and date. Removing her can require your approval.
“Send a test email to me and show me how it renders first.”
It sends with dry_run set so the email is only rendered, then sends it for real when you say so.
“Which sub-accounts sent the most mail this month?”
It lists top senders by volume for sub-accounts and can read usage for any one of them.

Questions

What can the AI do in MailChannels?

The AI can send email, check a sending domain, create and list DKIM keys and change their status, and add, list and remove suppressions. It can read performance, engagement, recipient behaviour and volume metrics, account and sub-account usage, sub-accounts, top senders and tracking domains.

Does the AI see my MailChannels credentials?

No. Your MailChannels API key is encrypted at rest and never shown to the AI. After you save it, it is not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start with metrics only. Sending email reaches real recipients, and removing a suppression lets an address be mailed again. Both can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your HeyMyApps link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

HeyMyApps has a free plan with no credit card required. Paid plans bill per completed task. You also need your own MailChannels account.

Why does sending fail for my domain?

MailChannels requires your sender domain to be set up with Domain Lockdown. Ask the AI to check the domain: it reports the DKIM, SPF and Domain Lockdown setup and whether mail from the domain will be accepted. Your API key also needs the scopes for the tools you use.
