The Top 10 Twilio SendGrid Alternatives for Your Transactional Emails

If you are interested in sending transactional emails, the chances you’ve heard about Twilio SendGrid are high. While the platform offers a wide range of features designed to assist in delivering your business messages to customers, there are other solutions that have speed, deliverability, and security as top priorities.

In this blog post, we’ll explore the best alternatives to Twilio SendGrid in terms of their features and pricing so that you can identify the best option for you.

Twilio SendGrid features and capabilities

Before jumping into discussing SendGrid competitors, let’s see what this platform has to offer.

Twilio SendGrid, formerly SendGrid, is a cloud-based email delivery and marketing platform that provides tools to send and manage business messages effectively. It lets you take advantage of email delivery, campaign management, testing, reporting, analytics tools, etc. Besides, this popular transactional email platform offers two email transfer methods: Rest API and SMTP relay.

Other SendGrid features and pros include:

  • Email templates and HTML coding. With SendGrid, you can use any of these options or combine them to streamline your email design process.
  • Email automations. It’s possible to craft automated email flows using triggers and a centralized view of your message series and timing.
  • High deliverability. The platform states an average inboxing rate of 96%. You can also manage your reputation with dedicated IP addresses and customized domains.
  • APIs and SDKs. SendGrid provides APIs and software development kits for various programming languages, making it developer-friendly and adaptable to different tech stacks.
  • Scalability. You can deliver more than 100 billion emails monthly on a customized plan.
  • Security compliance. Twilio SendGrid adheres to email marketing regulations, such as GDPR and the CAN-SPAM Act, that are vital to protect a brand’s reputation.
  • Support and documentation. The service offers customer support and extensive documentation to assist users in setting up and optimizing their email campaigns.

Speaking of Twilio SendGrid’s cost, a free plan is limited to 100 emails per day. The cheapest prepaid plan, allowing you to send up to 50,000 emails monthly, starts at $19.95/month.

Twilio SendGrid disadvantages

SendGrid may appear enticing due to its extensive functionality in transactional email marketing. At the same time, it’s always advisable to compare the pros and cons to identify whether the service is the best fit for you.

Let’s look at some reasons for businesses to be looking for Twilio SendGrid alternatives in more detail:

  • Cost. If you want to send transactional, marketing, and automated emails, you need to pay for separate plans. Transactional email plans start at nearly $20/month, and email marketing plans, including automated and drip campaigns, start at $60/month. Combined, Twilio SendGrid will cost you much more than its all-in-one alternatives.
  • Short email sending history. With only a 3-day email log, evaluating your email performance becomes rushed with unsatisfactory results. To access at least seven days of activity history, you have to upgrade to a Pro plan starting at almost $90/month.
  • Limited marketing channel options. If you’re considering other marketing channels, such as SMS, push notifications, or chats, you’ll have to invest in costly add-ons.
  • One teammate per account. To allow more users to send emails from a single SendGrid account, you have to upgrade to at least a Pro plan.
  • Subpar customer service. Depending on your subscription, there are different support channels available. For example, Free plan users can get help from the support team only through web tickets, while Essential plan users can also use a live chat. However, many users have expressed dissatisfaction in their SendGrid reviews, reporting a decline in responsiveness over time, even on paid add-on plans.

On different review websites, you can check feedback from real SendGrid users. Here is an example:

Twilio SendGrid customers also often report about having their dedicated IP addresses blacklisted. This means that the majority of messages end up in recipients’ spam folders, which probably doesn’t match any marketer’s expectations. Here is a SendGrid review about this issue:
