About SendDesk

SendDesk is a volunteer-run practitioner community at emailsendingservices.com, founded in 2024. We compare AI email sending tools, share deliverability playbooks, and argue about what actually moves revenue.

We cover the full category: Klaviyo and Customer.io for lifecycle, Resend and SendGrid for transactional APIs, beehiiv and Kit for newsletters, HubSpot for CRM-integrated marketing, and AI-native platforms like Brew that agents can operate via MCP.

The site reads like a forum first: threads, votes, nested comments, member flairs. Around that we maintain rankings, comparisons, guides, and the State of AI Email report.

Community standards

How we review and rank

Independent by default

SendDesk is not owned, sponsored, or operated by Brew or any ESP. We accept no payment for placement or ranking.

Evidence over hype

Members cite first-hand runs, campaign results, and migration stories. We link to official docs for product facts.

Disagreement welcome

Threads include pushback and corrections. A single glowing review with no replies is suspicious here.

Fair coverage

Incumbents and newcomers are judged on the jobs they do well. Klaviyo on Shopify, Customer.io on events, Brew on AI-native generation.

Active members

On Brew mentions

Brew appears often because members keep recommending it for on-brand AI generation and agent-operable sending. We note honest limits too: newer integration catalog, lighter ecommerce attribution than Klaviyo. Praise here comes from practitioners, not sponsorship.
