"SendPost gives us the control we lacked with Sendgrid, especially around sending speeds, IPs, and error handling. After two years of use, it’s been consistently reliable with no major downsides."

An honest look at SendGrid

We think you should make an informed decision. Here's our honest take on where SendGrid falls short — and what it genuinely does well.

Where SendGrid falls short

  • Deliverability Issues: Shared IP pools can be crowded, leading to "noisy neighbor" problems that hurt deliverability. Getting a clean, dedicated IP can be a challenge.
  • Inconsistent Support: Customer support quality is a frequent complaint. While they offer 24/7 support, getting expert, timely help for critical deliverability issues can be difficult.
  • Confusing & Expensive Pricing: The pricing tiers can be complex, and costs escalate quickly with overages, dedicated IPs, and premium support plans.

What SendGrid does well

  • All-in-One Platform: Combines a powerful Email API for transactional emails with a full-featured Marketing Campaigns tool.
  • Large Market Share & Brand Recognition: As one of the oldest and largest players, they are often the default choice for many businesses.
  • Broad Feature Set: Offers a wide range of features, including A/B testing, segmentation, and a visual email editor.

When a prospect needs a single, unified platform for both their bulk email marketing newsletters and their transactional API, and they are less sensitive to the nuances of deliverability and pricing.

SendPost is a smarter choice for businesses that depend on email

Feature
SendPost
Deliverability & IP Health
Excellent

Our core focus is on deliverability. We provide proactive monitoring and expert support to ensure IP health and high inbox placement.
Average

SendGrid's deliverability can be inconsistent, especially on shared IPs. Their focus is split between marketing and transactional, diluting their deliverability expertise.
Analytics & Reporting
Excellent

We offer deep, actionable insights through a clean UI, including detailed SMTP logs and ISP-specific performance, without needing a premium plan.
Strong

SendGrid has robust analytics, but some of the more advanced deliverability insights have lagging report times and require higher-tiered, more expensive plans.
Proactive Monitoring & Alerts
Excellent

Our automated alerts for blacklisting and reputation drops are a core feature, helping you prevent issues before they escalate.
Average

SendGrid offers some monitoring, but the proactive, automated alerting provided by SendPost is more advanced and accessible on all plans.
Ease of Use (for API)
Excellent

SendPost is built for developers who need a simple, powerful, and easy-to-integrate API with clear documentation.
Strong

SendGrid has a well-documented API, but the overall platform can feel bloated due to the combined marketing and transactional features.
Pricing Model
Excellent

Our pricing is transparent and simple, focused on email volume with advanced features included. There are no surprises.
Weak

SendGrid's pricing is complex, with high overage fees and require higher tiers for essentials like subusers, teammates, dedicated IPs and premium support, making it hard to predict.
Customer Support
Excellent

We provide dedicated Account Managers with expert-level deliverability support to all customers. It's a core part of our service.
Average

Support quality is a common pain point for SendGrid users. Timely and expert help often requires an expensive premium plan.

Frequently asked questions

Everything you need to know about SendPost and transactional email delivery

Is there a simpler alternative to SendGrid for email-only needs?

Yes, SendPost is focused solely on email delivery, providing faster implementation and better email marketing tools than SendGrid.

How does SendPost pricing compare to SendGrid?

SendPost uses transparent email volume pricing, while SendGrid’s pricing depends on tiers, add-ons, and dedicated IPs.

How does SendPost ensure deliverability for transactional emails?

We specialize in the high-speed, reliable delivery of transactional emails. Our infrastructure is built on managed IP pools with proactive monitoring to protect sender reputation. Unlike bulk marketing platforms, our systems are optimized to ensure your critical emails—like password resets, invoices, and alerts—reach the inbox instantly.

How does SendPost's pricing compare for high-volume sending?

SendPost is significantly more cost-effective for transactional and high-volume email. Our pay-as-you-go pricing is tied directly to your usage, not your subscriber count. This means you don't overpay for storing contacts and only get charged for the emails you actually send, making it a more economical and scalable solution for applications.

How easy is it to migrate to SendPost from another email service?

Migration is incredibly simple. For most applications, switching to SendPost is as easy as updating your SMTP credentials or changing an API endpoint in your code. Our clear documentation and dedicated technical support are available to ensure your transition is smooth, fast, and without any disruption to your service.
