Bird: User reviews & features

Bird is the company formerly known as MessageBird — an omnichannel communications platform in which email is a core product, which places it in our transactional test line. bird.com is the brand apex and served the platform directly when we verified it in August 2026. The company also absorbed SparkPost: sparkpost.com now redirects permanently to Bird's email product page, so the retired SparkPost brand's catalog entry points here. Our demand figure for Bird is a floor, since part of its search volume still arrives under the old MessageBird name. Pricing at our normalization volume has not yet been captured, so no price level is assigned.

Scored 0–100 from public evidence: an official MCP server weighs most (40, +5 when hosted), then official agent skills, AI assistant apps, AI-friendly docs and built-in AI features. "Not found" means we couldn't locate it on Bird's public pages or the official MCP registry, not that it can't exist. This is context, never part of the Deliverability Score.
