Pros & Cons

Mailgun logo
Mailgun

Pros

  • Reviewers repeatedly praise the REST API and documentation as quick for developers to integrate.
  • Deliverability and detailed per-domain searchable logs get strong marks from users.
  • SOC 2 Type II and ISO 27001 certification, with 2FA, SAML SSO and AES-256 encryption at rest.
  • A low entry price and a free tier of 100 emails a day for testing.

Cons

  • It is API-first and complicated for non-technical users, with a dated dashboard where settings and logs can be hard to find.
  • Several 2025 reviews report automated account suspensions with little warning.
  • Short log retention on lower plans (1 day on Free and Basic).
  • Reviewers call it costlier than rivals once volume grows, and inbox placement tools are a separate product.

Pros

  • The free plan gives unlimited users on a single app, so a team can run the CRM at no license cost.
  • CRM data flows natively into Odoo's Sales, Inventory, Invoicing, and Email Marketing apps, so quotes and stock checks happen without third-party connectors.
  • Lead tools go beyond the basics, with predictive scoring, quota-based assignment, deduplication, and enrichment.
  • It is open source and highly customizable through Studio, the API, or self-hosting.

Cons

  • Reviewers often describe the interface and workflows as complex for new users.
  • Setup usually needs internal staff or a paid implementation partner.
  • Some users report slow performance with large datasets.
  • Opinions on support and documentation quality are mixed, and paid support is email-only on weekdays.
