Tellnod is added as a custom connector [T3]. Brevo also covers SMS and CRM [B4]. - **Klaviyo:** far deeper automation, with tools across campaigns, flows, profiles and reporting [K1]. Tellnod has no automated flows yet [T4]. - **Constant Contact:** a live desktop and mobile preview in the chat, like Tellnod’s, on an established platform [C1]. - **Mailchimp:** plans campaigns from your own audience and campaign history inside an established app [M1]. - **Sequenzy:** a larger free email allowance, unlimited contacts on every plan, and sequences [S1][S3]. - **All five:** a longer public record than Tellnod, which is new and has no published customer results. ## Where Tellnod fits - You have no email platform yet and want setup, brand and contact import in the same conversation [T4]. - You want to send from the chat, with the recipient count, exclusions and send time on a card in front of you [T2]. - You run a small online shop such as Ninefold, sending a few one-off campaigns a month, and you can do without automated flows for now. ## Which one to choose - **You already use one of these platforms:** start with its own connector; your contacts and history are already there. - **You want a free connector and will send from the platform’s app:** Brevo [B1]. - **You rely on flows and detailed segmentation:** Klaviyo [K1]. - **You run a SaaS product:** Sequenzy describes itself as built for SaaS [S4]. - **You are starting from nothing and want the campaign finished in the chat:** Tellnod [T1]. ## FAQ ### Which Claude email connectors can send a campaign from the chat?
