When should you choose Sequenzy?
Sequenzy is the better choice when you need more than just transactional email delivery:
SaaS founders who want marketing automation + transactional in one platform
Non-developers who need visual email builders, not HTML templates
Stripe-powered businesses that want automated emails based on billing events
Small teams that prefer subscriber-based pricing over per-email costs
Marketing-focused companies that need campaigns, sequences, and segments
When should you stick with Mailgun?
Mailgun is the better choice for pure transactional email at scale:
Developers who want mature REST + SMTP APIs with 10+ years of reliability
High-volume senders who prefer pay-per-email pricing
Teams needing inbound email parsing for support tickets, etc.
Companies requiring email validation to clean lists before sending
Enterprises needing dedicated IPs for reputation isolation
Applications needing SMTP relay as a drop-in replacement
Honest Limitations of Sequenzy
No built-in email validation service
No inbound email parsing for reply handling
Dedicated IPs only available for enterprise customers
Newer platform (less battle-tested than Mailgun's 10+ years)
No send time optimization AI
Honest Limitations of Mailgun
No marketing automation—purely transactional
No visual email builder (HTML templates only)
No campaign management or broadcast features
No subscriber segmentation for marketing
Email costs can add up at scale (per-email pricing)
Requires Mailchimp for marketing features (different platform)
