What you can automate today

Redbird gives your team ready-to-run workflows — just connect your accounts and go.

Sync high-engagement cohorts from Amplitude to Mailchimp as targeted segments

Automatically create Mailchimp audience segments from Amplitude behavioral cohorts—users who completed key events, hit retention milestones, or match specific product usage patterns. Segments update continuously as user behavior changes, eliminating manual list exports and outdated targeting.

Trigger onboarding emails when users complete activation events in your product

Launch personalized Mailchimp campaigns or automation sequences the moment Amplitude registers critical product events—first feature use, setup completion, or activation milestones. No more batch-and-blast onboarding or delayed follow-ups based on stale signup data.

Re-engage dormant users with win-back campaigns based on retention analysis

Identify users who've dropped off key engagement patterns in Amplitude and automatically add them to Mailchimp re-engagement flows. Surface churn signals like declining login frequency or abandoned features, then trigger tailored campaigns to bring them back.

Enrich Amplitude profiles with email engagement data from Mailchimp campaigns

Push Mailchimp opens, clicks, and campaign interactions back into Amplitude as user properties and events. Analyze how email engagement correlates with product behavior, measure the downstream impact of marketing sends, and build cross-channel attribution models.

Alert product teams when feature adoption email campaigns drive conversions

Track which Mailchimp campaigns successfully drive users to adopt new features or complete product goals in Amplitude. Surface campaign performance tied to actual product outcomes, not just open rates, so growth teams know which messaging works.

Update Mailchimp subscriber tags based on product lifecycle stage transitions

Automatically tag Mailchimp subscribers when they move between lifecycle stages in Amplitude—trial to paid, new to activated, power user to at-risk. Keep email segments aligned with actual product behavior without manual tag management or scheduled batch updates.

Live in four steps

No engineers, no pipelines to maintain. Redbird handles the connectivity — you focus on the outcome.

01

Connect your accounts

Authorize Amplitude and Mailchimp with OAuth or API credentials. Redbird never stores your data — it just passes through.

02

Describe what you want

Tell Redbird what to do in plain language — no SQL, no code, no configuration files required.

03

Review and activate

Redbird shows you exactly what it will do before running anything. Approve the workflow, set a schedule, and switch it on.

04

Let it run — and iterate

Workflows run on your schedule or on triggers. Every run is logged. Adjust with natural language at any time.

Built for data-driven teams

Redbird understands Amplitude's event taxonomy and user properties alongside Mailchimp's audience structure, merge fields, and automation triggers—so you can move product intelligence directly into your marketing stack.

AI that speaks both product analytics and email marketing

Redbird maps Amplitude events, cohort definitions, and user properties to Mailchimp segments, tags, and merge fields without custom code. It handles data type mismatches—like converting timestamp properties to Mailchimp date fields or translating boolean flags into tags. The AI knows when to batch updates to respect rate limits and when to trigger immediate sends for time-sensitive product events. It even reconciles user identities across systems when email addresses don't match Amplitude user IDs.
