Deliverability & Performance: Which One Lands More Emails in the Inbox?

Email deliverability is a crucial factor when choosing an email platform. It determines whether your emails successfully land in the recipient’s inbox instead of being filtered into spam or promotional folders.

Both SendGrid and Mailchimp have strong reputations for deliverability, but their approaches are different. Let’s break down which platform ensures your emails actually reach your audience.

A. How SendGrid Ensures High Deliverability

✔ Dedicated IP Option:

• SendGrid allows dedicated IP addresses (available on Pro and Enterprise plans) for better sender reputation management.
• This is essential for businesses sending high volumes of emails (e.g., transactional emails, newsletters).

✔ Advanced Authentication (SPF, DKIM, DMARC):

• SendGrid provides tools to properly authenticate emails, reducing the risk of them being marked as spam.
• SPF, DKIM, and DMARC setup improves inbox placement rates.

✔ Reputation Monitoring & IP Warming:

• SendGrid offers IP warming to gradually increase sending volume, helping new senders avoid deliverability issues.
• Their reputation monitoring dashboard helps users track email performance.

✔ Best for Transactional Email Deliverability:

• Since SendGrid is API-based, its emails are sent quickly and reliably, making it the preferred choice for transactional emails (e.g., password resets, order confirmations).

❌ Potential Downsides:

• Setting up SPF, DKIM, and DMARC requires technical knowledge.
• Shared IPs (on lower-tier plans) may impact deliverability if other users on the same IP have bad practices.

✅ Verdict:
SendGrid is the best option for businesses needing high deliverability rates, especially for transactional emails.

How Mailchimp Ensures High Deliverability

✔ AI-Powered Send-Time Optimization:

• Mailchimp uses machine learning to determine the best time to send emails based on user engagement patterns.
• This improves open and click-through rates.

✔ Spam Filter Warnings & Compliance Features:

• Mailchimp scans your email content before sending, warning you if words, images, or links may trigger spam filters.
• This helps marketers avoid the spam folder.

✔ Email Reputation Managed by Mailchimp:

• Unlike SendGrid (where you manage your own sender reputation), Mailchimp handles reputation and authentication for you.
• This makes it easier for non-technical users but also means less control over deliverability settings.

✔ Best for Marketing & Newsletter Emails:

• Mailchimp is optimized for promotional and marketing campaigns, where engagement (opens, clicks) matters more than instant delivery.

❌ Potential Downsides:

• Uses shared IP addresses for most users, which means your email reputation is tied to other senders.
• Not designed for high-volume transactional emails—if you send frequent order confirmations or account notifications, Mailchimp may not be the best choice.

✅ Verdict:
Mailchimp is great for marketers and businesses looking for AI-driven send-time optimization and spam filter protection.

Deliverability Test: Who Wins?

Final Verdict: Which One Has Better Deliverability?

• SendGrid is better for businesses that send high volumes of transactional emails and need full control over email authentication and deliverability.
• Mailchimp is better for marketers who want easy-to-use deliverability features and AI-driven email optimization but don’t need advanced reputation management tools.

Key Takeaways: Which One is Right for You?
