How to choose in five questions
Where do you want to work?
In the AI assistant you already use, or in a dedicated marketing dashboard? If it is the assistant, start with Tellnod.
Do you need automated flows today?
If welcome series and cart flows already drive a large share of your orders, stay with a flow-first platform such as Klaviyo. If you send campaigns a few times a month, you do not need them yet.
Which channels do you need?
Email only, or SMS and WhatsApp as well? Brevo's MCP documentation covers email, SMS and WhatsApp campaigns S3; Tellnod starts with email and adds WhatsApp next.
Who presses send?
If an AI assistant will help you, check how sends are approved. In Tellnod the assistant can only prepare a send; you confirm it on a card.

FAQ
What is the easiest Klaviyo alternative to set up?
If you already use Claude or ChatGPT, Tellnod: you add it as a connector, sign in with Google and set up your brand, contacts and domain in the same conversation, with no card and no dashboard to learn.
Is there a free Klaviyo alternative?
Several tools have free plans. Tellnod plans a free tier for up to 500 contacts and 2,000 emails a month; check each tool's pricing page for current limits.
