Brevo and Amazon Simple Email Service (SES) address overlapping needs for sending email at scale but target different priorities: Brevo combines a marketing automation platform with an easy-to-use sending stack, while Amazon SES focuses on high-throughput, low-cost transactional sending. The following analysis compares deliverability, configuration, costs, migration steps, and regional compliance for teams operating from England in 2025–2026. Decision-makers will find benchmark data, a migration checklist, TCO scenarios, and practical configuration instructions.
Overview and core differences
- Brevo (formerly Sendinblue) targets marketers and SMBs that need email campaigns, automation, SMS, and a starter transactional layer with visual editors and built-in analytics. Useful when marketing automation and audience tools matter.
- Amazon SES targets engineering teams and high-volume senders who require a flexible, API-first, cost-efficient transactional service with deep AWS ecosystem integrations.
Key technical contrasts
- Interface: Brevo provides a UI-first experience with drag-and-drop editors and campaign reporting. Amazon SES exposes APIs and SMTP endpoints designed for programmatic control and integration with other AWS services.
- Deliverability controls: Brevo offers managed deliverability and inbox placement features. Amazon SES offers granular IP management (dedicated IPs via SES V2), reputation dashboards and integration with Amazon Reputation Dashboard.
- Pricing model: Brevo bundles marketing features with sending tiers. Amazon SES separates sending costs (pay-as-you-go) and charges based on data transfer in some cases.
Deliverability benchmarking and reproducible tests
Methodology for reproducible inbox placement tests
A rigorous benchmark should include:
- Seed lists across major mailbox providers (Gmail, Outlook/Hotmail, Yahoo, Apple Mail).
- Matching message content and volume from both platforms.
- Authentication parity: identical SPF, DKIM, and DMARC records.
- IP scenarios: shared vs dedicated IPs, warmed vs cold IPs.
- Measurement windows (7, 30, 90 days) and complaint rate tracking.
Sources for best practices include the Google Postmaster and AWS guidance in Amazon SES Developer Guide.
Summary of independent test findings (2025–2026)
- Inbox placement: When authentication and sending patterns are equivalent, Amazon SES with warmed dedicated IPs performs marginally better for high-volume transactional flows to Gmail and Outlook in 2025–2026 datasets. Brevo performs strongly for mixed marketing traffic and maintains competitive placement on major providers thanks to managed vendor relationships.
- Complaint rates: Brevo’s integrated suppression management reduces repeat sends to known complainers; SES requires application-level suppression handling unless SES features are used.
- Latency and throughput: SES API endpoints show lower median latency and higher throughput under concurrent workloads, consistent with AWS infrastructure.
Benchmark sources and raw seed-list methodology are available from deliverability vendors and should be reproduced for enterprise decisions.

Included in Brevo plans |
Requires additional tooling (third-party, higher TCO) |
| Support / SLA |
Paid support tiers with faster SLAs |
AWS Support plans (Developer/Business/Enterprise) add significant cost |
TCO scenarios
- Low volume marketing-led (50k/mo): Brevo tends to be lower TCO due to included features and UI.
- High-volume transactional (5M+/mo): Amazon SES usually has lower pure sending cost; however, costs for monitoring, IP warm-up, and engineering time must be included.
- Hybrid (marketing in Brevo + transactional in SES): Often lowest combined TCO for teams that separate responsibilities.
Cost factors beyond per-message price
- Engineering hours for integration and maintenance
- IP warm-up and reputation management overhead
- Data residency and logging retention needs for compliance
- Third-party deliverability tools and seed lists
Migration and configuration playbook (step-by-step)
Migration checklist: Brevo → Amazon SES (practical)
- Inventory current sending: templates, suppression lists, contact segments.
- Export templates and subscriber lists with consent metadata.
- Configure DNS: SPF, DKIM, and DMARC records for SES domains. See AWS DKIM setup.
- Implement SES API or SMTP integration code paths, preserving tracking parameters.
- Recreate suppression logic (bounces, complaints) in application or use SES suppression features.
- Warm up IPs using staged ramp-up scripts and scheduling.
- Run parallel sends and seed-list tests for 7–14 days before cutoff.
- Decommission old sending only after data reconciliation and DNS TTL considerations.
Configuration snippets and integration notes
- For SMTP, SES supports standard authentication. For API, SES V2 supports SendEmail and other endpoints for templated sending.
- Ensure strict hashing and consent logging when transferring subscriber data to meet GDPR requirements; reference gdpr.eu for record-keeping recommendations.
Migration pitfalls and mitigation
- Lost consent metadata: Preserve timestamp and source for each recipient.
- Cold IPs: Avoid moving large volumes to new IPs without staged warm-up.
- Tracking parity: Email open/click tracking differs—plan for analytics reconciliation.
Authentication, reputation and compliance
SPF, DKIM, DMARC best practices
- Publish SPF including third-party ESPs. For SES: include region-specific SES sending domains in SPF.
- Enable DKIM signing for every sending domain. SES supports Easy DKIM and brings granular control; Brevo supports DKIM via account settings.
- Publish a strict DMARC policy after monitoring with p=none for 30–90 days, then escalate to p=quarantine or p=reject.
IP management and warm-up
- Warm-up schedules should follow a ramp pattern, doubling daily volume while monitoring complaints and bounces.
- Consider dedicated IPs for transactional traffic with high deliverability SLAs.
GDPR and data residency
- Brevo operates EU data regions and provides GDPR-focused features for England/EU customers. Confirm region specifics on the product pages.
- AWS supports regional SES endpoints; verify that chosen AWS region aligns with data residency and legal requirements.
- Use documented data processing addendums and ensure contractual guarantees for processing locations.
Use cases, recommendations and decision matrix
When to choose Brevo
- Teams prioritizing a unified marketing platform, drag-and-drop campaign creation and out-of-the-box deliverability assistance.
- Organizations seeking fast time-to-market with less engineering overhead.
When to choose Amazon SES
- High-volume transactional senders needing cost efficiency and deep API control.
- Engineering-led teams that require flexibility, performance and integration with other AWS services.
Hybrid recommendation
- Use Brevo for marketing campaigns and Amazon SES for transactional messages to optimize both cost and feature sets. This split reduces risk and enables specialist handling of deliverability for each message category.

Frequently asked questions
Can Brevo match SES for high throughput transactional sending?
Brevo can handle transactional volumes but may be costlier at very high volumes. Amazon SES scales more efficiently for millions of messages with lower per-message cost and higher throughput guarantees.
How to ensure GDPR compliance when switching providers?
Preserve consent metadata, sign appropriate data processing agreements, select EU regions when available, and document legitimate interest or consent records. Reference contractual terms and privacy pages of each provider before migration.
With equivalent authentication and warmed IPs, SES often edges ahead for pure transactional flows at scale. Brevo maintains competitive placement for mixed marketing traffic because of managed relationships and active suppression handling.
Is a hybrid setup (Brevo + SES) recommended?
Yes. A hybrid approach separates marketing and transactional workloads, optimizing cost and deliverability while preserving features. This reduces scope for risk to transactional reputation.
What is the typical warm-up schedule for a new dedicated IP?
Start with a small daily volume and increase sends by 50–100% every 24–48 hours while monitoring complaint and bounce rates. Adjust conservatively based on mailbox provider responses.
Conclusion
Choosing between Brevo and Amazon SES depends on priorities: marketing features and ease-of-use favor Brevo; low per-message costs, high throughput and deep programmable control favor Amazon SES. For teams in England concerned about compliance and regional handling, both platforms offer viable options when configured correctly. A documented migration plan, robust seed-list deliverability testing, and a hybrid architecture for distinct use cases provide the most resilient outcome in 2026.
