Small or mid-market dev teams — the product is no longer positioned for under 1M emails/month and pricing is sales-led only.
Enterprise senders above 10M emails/month who need real-time analytics, dedicated deliverability engineering, and the underlying Momentum MTA pedigree.
Why we say this
Editorial pulled these weaknesses from SparkPost’s product card in our Top 10 Transactional Email Software for 2026:
- ! Pricing fully opaque; sales engagement required
- ! Lower tiers (under 1M emails/month) deprecated in 2022; product is now enterprise-only
- ! Bird acquisition has introduced CPaaS cross-sell narrative around what was a transactional-only product
- ! Dev mindshare has shifted to Postmark and Resend for newer projects
- ! Documentation depth uneven post-acquisition per recent reviews
