Chances are you were once interested in SendGrid for its reputation as a transactional email service provider or SMTP (Simple Mail Transfer Protocol) service provider.

While it’s true that big-name brands are still putting aside leaving the platform, SendGrid has been a questionable choice for small to medium businesses (SMBs) for a while now.

Read on to learn about the best SendGrid alternatives and what they have to offer. But before we start, let’s see why people consider switching from SendGrid in the first place.

Why Consider SendGrid Alternatives?

SendGrid might look attractive to its famous clients. After all, if something like Yelp is using it, it must be good, right? Unfortunately, SendGrid seems to keep riding on the same wave, offering little improvements over time, prioritizing the big names, and getting rather costly.

Let’s look at some ecommerce businesses’ reasons for leaving SendGrid in more detail:

  • Expensive. The essentials plan starts from a relatively high $20 per month. What you get in return is just a drop of all features;
  • Only a 3-day email log. Log retention can be used in evaluating your email performance. Just three days mean you have to hurry for unsatisfactory results or pay for a 30-day log history extra to an already costly service.
  • Restrictive marketing channel diversification. If you wish to explore other high-converting marketing channels like SMS messages, push notifications, or chats, you’ll need to invest in not-so-cheap add-ons.
  • Unsatisfactory customer service. Many users have reported that SendGrid’s support has worsened, and their phone support (on higher plans) is often unresponsive.
  • Blacklisted IPs. This one is a huge no-no in the email marketing context. If dedicated IP addresses are blacklisted, most marketing messages will go straight to the spam folder.

7 Best SendGrid Alternatives for Marketers & Developers

If you’re searching for email marketing software like SendGrid, you should consider the following tools: 

1. Sender – Best SendGrid Alternative for Omnichannel Campaigns

Sender is at the top of our SendGrid alternatives list for a good reason — it’s a powerful email and SMS marketing tool with an intuitive email builder. Plus, human customer support ensures you get real solutions and don’t waste time talking to a robot.

Best for:

  • Small and medium business owners; 
  • Ecommerce stores; 
  • Email marketing beginners.

Plus, it has all the features needed for omnichannel campaigns: a drag-and-drop email design tool, SMS/email marketing automation builder, popup creator, and smart segmentation. You get everything needed to get you going within a day (or less). 


You can easily set up automation campaigns based on smart segmentation, such as those for abandoned carts, winback emails, follow-ups, and cross-selling. 

Sender offers access to all the premium features, even on the free plan. So, you can scale without any hidden costs, making it a useful SendGrid alternative for small businesses.

  • Financial firms. 

Postmark offers premade email templates to streamline communication. One interesting feature offered by the tool is message streams. It prevents email mixing, improving traffic management and deliverability. Plus, Postmark’s reliable SMTP relay server ensures fast delivery to popular email clients.

With detailed reporting and a 45-day log retention period, Postmark provides users with valuable insights into their email campaigns. Though Postmark maintains a separate infrastructure for transactional and bulk emails, it lacks standard campaign-building features.

  • Technology startups.

While lacking advanced email marketing features, SES compensates with essential tools such as the Virtual Deliverability Manager for automated inbox optimization and a Mailbox Simulator for scenario testing.

Amazon SES stands out from its competitors, emphasizing simplicity and cost-effectiveness. It operates on a pay-as-you-go pricing model that adjusts to users’ needs, ensuring affordability.

Its authentication options, including SPF and DKIM, ensure high deliverability rates, while activity and sender reputation monitoring features enable effective email performance tracking.

With advanced multi-step sequences available at higher-tier plans, Mailchimp Transactional Email is a versatile solution for businesses seeking a reliable platform for transactional email needs.

One key feature that sets Mailgun apart is its InboxReady toolkit. This toolkit enhances email deliverability through verification, pre-send testing, and precise inbox placement tracking. 

Despite lacking dedicated email marketing tools like other alternatives, Mailgun compensates with exceptional deliverability rates. However, its lack of critical email marketing features makes it a good solution only for developers/marketers looking for a transactional email API.
