Pricing Comparison

Tie

SendGrid uses volume-based pricing for transactional email:

  • ●Free: 100 emails/day
  • ●Essentials: From $19.95/month for 50K emails
  • ●Pro: From $89.95/month with dedicated IP

Mailchimp uses contact-based pricing:

  • ●Free: 500 contacts, 1,000 sends/month
  • ●Essentials: From $13/month for 500 contacts
  • ●Standard: From $20/month with advanced automation

Winner: SendGrid for high-volume senders, Mailchimp for small lists

Contact-based pricing (Mailchimp) gets expensive fast if you have many subscribers. Volume-based (SendGrid) is better for large lists with moderate send frequency.

Transactional Email

SendGrid wins

SendGrid was built for transactional email:

  • ●Robust API with excellent documentation
  • ●SMTP relay support
  • ●Real-time analytics and webhooks
  • ●Built-in email validation

Mailchimp added transactional later (via Mandrill):

  • ●Separate product requiring Mailchimp subscription
  • ●Good API but less developer-focused
  • ●More limited analytics
  • ●Additional cost on top of Mailchimp subscription

Winner: SendGrid

If transactional email is your primary use case, SendGrid is the clear choice. Mandrill feels like an afterthought bolted onto Mailchimp.

Marketing Email

Mailchimp wins

Mailchimp excels at marketing:

  • ●Drag-and-drop email builder
  • ●Pre-built templates and content blocks
  • ●Customer journey automation
  • ●Landing pages and signup forms
  • ●Built-in CRM

SendGrid has marketing features but they're secondary:

  • ●Email builder is functional but basic
  • ●Automation is limited
  • ●No built-in landing pages
  • ●Marketing features feel added-on

Winner: Mailchimp

For marketing-first teams who prioritize campaign creation and automation, Mailchimp provides a more polished experience.

Deliverability

Tie

SendGrid deliverability:

  • ●Large shared IP pools (risk of bad neighbors)
  • ●Dedicated IPs available at higher tiers
  • ●Good infrastructure but reputation varies
  • ●Some account suspension complaints

Mailchimp deliverability:

  • ●Strict content policies (protects reputation)
  • ●Shared infrastructure for most users
  • ●Generally good inbox placement
  • ●Can be aggressive with account terminations

Winner: Tie

Both have solid infrastructure, but both suffer from shared IP issues on lower tiers. Neither offers the reputation isolation that modern platforms like Transmit provide.

Ease of Use

Mailchimp wins

SendGrid is developer-first:

  • ●Excellent API documentation
  • ●Code examples in multiple languages
  • ●Dashboard is functional but technical
  • ●Requires some technical knowledge

Mailchimp is marketer-first:

  • ●Intuitive visual interface
  • ●Little to no coding required
  • ●Extensive tutorials and guides
  • ●Better for non-technical users

Winner: Mailchimp

If your team doesn't have developers, Mailchimp is much more accessible. SendGrid assumes technical competence.

The Verdict

Choose SendGrid if you're a developer-led team prioritizing transactional email with API integration. The documentation is excellent and the pricing works better at scale.

Choose Mailchimp if you're a marketing team focused on campaigns and automation without technical resources. The visual builder and templates make campaign creation fast.

Neither is ideal if you need unified transactional and marketing with modern features like built-in warmup, reputation isolation, or BYOK options.

Consider Transmit

Both SendGrid and Mailchimp use shared infrastructure that puts your reputation at risk. Transmit offers **Multi-tenant Reputation Isolation** so one bad sender can't affect your deliverability, plus auto-pause on high bounce/complaint rates to protect your domain. Unified transactional and marketing email with automated warmup, no separate products or complicated pricing tiers.
