What connecting MailerSend unlocks

Transactional messaging joins your marketing chat

MailerSend sends transactional email and SMS from your domain. Connecting it puts that channel in the same conversation as your ads, landing pages, and campaign planning.

Copy Chief for the emails you forget about

Order confirmations, receipts, and notification texts carry your brand too. Run that copy through Copy Chief reviews and rewrite it with the same rigor as your ads.

Sends stay behind permissions you control

Sending email or SMS is a write action. StefanBrain classifies writes separately from reads, so nothing goes out without the tool permissions you set.

One brain across every channel

Your transactional channel stops living in a silo. Chat answers, creative work, and CRO analysis can factor in the messages customers already get from you.

Frequently asked questions

What can StefanBrain read from MailerSend?

The connection is scoped by the API key you provide, so StefanBrain gets what your key allows and nothing more. MailerSend handles transactional email and SMS from your domain, so questions about that channel are what this connection is for.

How does authentication work?

MailerSend connects with an API key rather than a sign-in button. The key comes from your MailerSend account or developer settings, and you paste it into the connection dialog in StefanBrain. If you rotate the key later, reconnect with the new one.

Can StefanBrain send email or SMS on its own?

Sending is what MailerSend does, and inside StefanBrain sending is a write action. Write actions are gated by tool permissions, so you can require approval or block them entirely. Nothing goes out without the access you granted.

How do I disconnect?

One click in Connectors removes the connection and StefanBrain's access with it. For a full stop, remove the key in your MailerSend account or developer settings as well, so the credential no longer works anywhere.

How is MailerSend different from MailerLite?

Despite the similar names, they cover different channels. MailerSend is for transactional email and SMS sent from your domain, while MailerLite manages subscribers and newsletters. StefanBrain offers both as separate connectors, so connect the one your stack actually uses.
