Migration Agent

Mailchimp → Brevo

Add optional context, then the agent writes a detailed plan and coaches it step by step. The full plan stays on this page. Talk to a specialist or a matched services partner when the cutover is too heavy.

Data to export from Mailchimp

  • synced email and calendar links
  • workflow rules
  • saved reports
  • campaign and automation records
  • AI assistant configuration
  • records for the catalog use cases: automation, lifecycle

How the catalogs differ

  • Neither product is flagged for custom objects. Keep the object list short.
  • Brevo adds catalog flags Mailchimp does not have: sequences and cadences.
  • Mailchimp is flagged with an open API, which is the export path to test.
  • Brevo is flagged with an open API for the load.
  • Mailchimp is cataloged as a fit for: SMB email.
  • Brevo is cataloged as a fit for: SMB email plus SMS.

Phases

  1. Export

    Take Mailchimp as the source of truth for this pair. Export synced email and calendar links; workflow rules; saved reports; campaign and automation records; AI assistant configuration; records for the catalog use cases: automation, lifecycle. The SMB email incumbent — audiences, campaigns, and a friendly on-ramp.

  2. Map

    Load into Brevo only after the field map is written down. Formerly Sendinblue — email, SMS, and a CRM-ish suite at SMB prices. Neither product is flagged for custom objects. Keep the object list short.

  3. Prove a sample

    Brevo scores 8/10 on speed to live and 6/10 on migration friendliness. Run one sample load and one report the team already uses in Mailchimp before a full cutover.

  4. Cut over

    Mailchimp scores 6/10 on migration friendliness and is marked low difficulty in the catalog. Keep Mailchimp readable until the team is working in Brevo. Mailchimp is how millions of SMBs still send email. It is an incumbent at a different altitude than Marketo. AI writing exists; the product is still campaigns and audiences. Teams leave it for Klaviyo-style commerce or AI-native content ops.

Afterstack is not the vendor. This agent does not move data, does not authenticate to Mailchimp or Brevo, and does not sell a rank. Methodology.
