And this isn’t possible without a reliable email marketing tool.

One such product that has established its name in the industry is SendGrid. It operates from Denver and serves customers across various sectors. However, considering its price tag, small to medium enterprises may hesitate to swing with it.

To make successful marketing accessible to all, here is the perfect alternative to SendGrid, along with detailed pricing and feature comparison.

What is SendGrid?

SendGrid is a popular email marketing and deliverability software that has helped thousands of businesses with reliable email communication.

  • Globally distributed cloud architecture ensures that any minor glitch doesn’t bring the whole system down. 
  • It has partnered with mailbox providers like Gmail, Microsoft, and Verizon Media.
  • It supports SPF records, custom DKIM, feedback loops, and dedicated IP addresses for better email deliverability.

What Makes SendGrid So Popular?

Here are some reasons that make its customers vouch for it.

1. Keeps Data Safe From Snoopers

SendGrid takes extra security measures to keep your data secure and private. It complies with standard security guidelines like SOC and GDPR.

The users’ accounts are additionally secured with API keys, two-factor authentication, and TLS encryption. It has also introduced Single Sign-on (SSO) to let the users manage account permissions.

2. Shoulders Heavy Traffic With Ease

SendGrid boasts of delivering over 7 billion emails on Cyber Monday without any issues. It sends over 100 billion emails on average every month.

A product that can handle such a high volume can do so only because of a dependable architecture. It also lets users scale their operations without waiting days to arrange relevant resources.

3. A Setup That Doesn’t Intimidate

SendGrid is known for its user-friendly interface and easy-to-use features. This makes it accessible to a broader market, with beginners to experienced professionals as its users.

Users can get started quickly with the ready-to-use library of responsive email templates. One can even design their own template with the drag and drop feature.

4. Allows Scalability At a Click

It also keeps the users updated with the latest trends and lets them optimize their operations for better results.

The Flip Side of SendGrid

While SendGrid is a popular and widely used email marketing and deliverability software, there are a few potential drawbacks one should consider. 

Here are some of the cons of SendGrid.

1. Pocket Will Get (a lot) Lighter

Depending on the business requirements for a custom service, SendGrid can be relatively expensive. Though bigger enterprises might not mind the cost of the features, a small or medium organization will have to think twice before committing to such an investment.

2. Customizations With Conditions

While SendGrid is a flexible and customizable platform, some users have reported that making certain types of customizations, such as to the HTML or CSS of their emails, can be challenging. It can limit the ability of businesses to fully adapt their emails to match their branding and design needs.

3. Limited Cross-Platform Integrations

SendGrid supports several integrations with other platforms and tools but lacks options compared to other email marketing tools. It can restrict businesses from creating a seamless solution for all their email communication needs.

4. Lack of Data to Back Deliverability Claims

SendGrid users have often reported that their transactional emails often get lost before reaching their destination.

It can be frustrating for businesses, as transactional emails are typically critical for communication with customers and clients.

The bottom line– while SendGrid is a powerful and versatile platform, it may not be the best fit for all businesses, especially those with limited budgets or specific customization or integration needs.

Small businesses: SendPost offers several features and services specifically designed for small businesses, such as its free plan, which includes up to 2,000 subscribers and 10,000 emails per month. It makes it a more affordable and accessible option for small businesses and startups.

Overall, SendPost may be a better fit than SendGrid for businesses that need a high level of customization with a wide range of integrations.

However, the best platform for a specific business depends on its needs and requirements.

Why Should You Choose SendPost?

SendPost is designed to address the challenges and frustrations associated with using email API/SMTP providers, particularly for businesses that send large emails. If you are sending only a few thousand emails per month, most email API solutions may work well for you, and you can choose one based on price, features, or support. However, sending millions of emails monthly and managing multiple sending domains, IP pools, and IP/domain reputation can be a significant headache if you are a large sender. Even a minor dip in your email open rate or deliverability can impact your revenue at that scale.

SendPost offers a solution that helps you understand and fix issues with your email deliverability quickly and easily. It provides alerts and notifications to help you stay on top of your deliverability and can even act on your behalf to prevent problems from occurring. With SendPost, you can rely on a reliable partner and powerful software that understands how critical email is for your business.
