How Groupmail Works with SendGrid and SMTP2GO

Groupmail integrates seamlessly with both SendGrid and SMTP2GO by using standard SMTP settings, making the setup process straightforward. All you need to do is input the SMTP server address, port, and authentication details for your chosen provider into Groupmail's account settings. Once configured, you're ready to send newsletters and transactional emails without hassle.

Both SendGrid and SMTP2GO support SMTP and API-based sending, giving you the flexibility to choose the method that aligns with your technical expertise and needs. Whether you're a small business owner launching email campaigns or a developer handling large-scale communications, the connection process is designed to be user-friendly.

After setup, Groupmail's tools - like drag-and-drop email design, campaign scheduling, and real-time analytics - work seamlessly with either provider. For detailed insights into delivery and engagement, such as open rates, bounces, and spam complaints, you can access the reporting dashboards provided by SendGrid or SMTP2GO.

One key difference lies in server locations. SMTP2GO operates servers in regions including the US, EU, Australia, New Zealand, and Singapore, which can improve delivery speed and reliability for global users. SendGrid, on the other hand, primarily relies on US-based servers. These variations in server locations can impact metrics like deliverability and performance, which are explored further in the next section.

Take note of attachment size limits: SMTP2GO allows up to 50 MB per email, while SendGrid supports up to 30 MB. Both services function exclusively as outbound relays.

The flexibility of Groupmail's setup means you can easily switch between providers with minimal adjustments. This allows you to test both options and determine which works best for your needs. It also ensures that you're not tied to a single SMTP service, offering adaptability as your business requirements change.

Pricing and Free Plans Comparison

In May 2025, SendGrid made a significant change by discontinuing its free plan entirely. This decision shifts the spotlight to SMTP2GO, which still offers a free plan, making it an attractive choice for testing email-sending capabilities without any upfront commitment.

Here’s a breakdown of the pricing details for both providers.

SendGrid Pricing

SendGrid now requires all users to start with a paid plan, as the free tier was discontinued in 2025. For Groupmail users seeking advanced features, SendGrid offers several options:

• The Essentials plan starts at $19.95 per month and includes up to 60,000 emails.
• For higher email volumes, the Pro plan begins at $89.95 per month, covering between 100,000 and 2,500,000 emails.
• Enterprise-level users can inquire about Premier pricing for custom solutions.
• Additionally, SendGrid provides separate Marketing Campaigns pricing, starting at $15 per month for up to 100,000 contacts and 300,000 emails. The Advanced tier costs $60 per month and supports 200,000 contacts and 1,000,000 emails.

SMTP2GO Pricing

SMTP2GO stands out with its free plan, which has no expiration and is ideal for small businesses or users exploring Groupmail's email marketing features. The free plan includes 1,000 emails per month with a daily limit of 200 emails. For those requiring more, paid plans start at:

• Starter plan: $15 per month for 10,000 emails.
• For businesses sending over 3 million emails monthly, SMTP2GO offers custom Premier pricing.

Pricing Comparison Table

SMTP2GO's Starter plan averages about $0.0015 per email, while SendGrid's pricing comes to approximately $0.00033 per email. However, SendGrid's higher minimum monthly cost makes SMTP2GO a better option for beginners or those with smaller email volumes.

For Groupmail users starting their email marketing journey, SMTP2GO’s free plan offers a low-risk way to grow a subscriber list and refine strategies before committing to a paid option. On the other hand, SendGrid’s lack of a free tier requires immediate investment, even for users with minimal email-sending needs.

Setup Process and Ease of Use

The setup process for SendGrid and SMTP2GO varies depending on how each service integrates with Groupmail. Your level of technical expertise and the resources you have on hand will play a big role in determining which service feels easier to set up.

Setting Up SendGrid

With SendGrid, domain authentication is a required step. This process involves updating DNS records to verify that you own the domain and to authorize SendGrid to send emails on your behalf. To do this, you'll need to log into your domain registrar, add the necessary DNS records, and then generate an API key within your SendGrid account for integration.

For users with certain DNS providers, like GoDaddy, SendGrid simplifies this process by offering automated domain setup. If your provider isn't supported, you'll need to manually input the DNS records into your domain settings.

Setting Up SMTP2GO

SMTP2GO takes a more straightforward approach, particularly for Groupmail users. The platform includes a streamlined integration process with Groupmail Web, allowing users to sign up for a free account directly from the Groupmail interface. This minimizes the number of steps and reduces the need to navigate away from the platform.

To complete the setup, you’ll need to provide an API key, verify your From Email address, and input a Webhook URL. SMTP2GO’s setup guide is designed to prioritize simplicity and speed, making it a great option for those who want to get started quickly.

Additionally, SMTP2GO offers general SMTP setup instructions and platform-specific guides, including dedicated documentation for Groupmail.

Setup Comparison Table

Both providers offer robust support during the setup process. SendGrid provides extensive documentation and technical troubleshooting for its General Availability products, along with 24/7 live chat and callback options for paid users. Free users can still access ticket-based support.

SMTP2GO, on the other hand, offers live chat, email, and phone support. However, free plan users are limited to email ticket support after the initial 14 days. Their setup guides and direct assistance can be especially helpful for users looking for a quick and hassle-free configuration experience.

Email Delivery and Customer Support

Ensuring reliable email delivery is a cornerstone of any successful Groupmail campaign. Both SendGrid and SMTP2GO excel in this area, though their approaches to dedicated IPs and support vary. Let’s dive into how each provider handles delivery and support.

SendGrid Email Delivery

SendGrid offers flexibility with both shared and dedicated IP options, tailored to your sending volume and plan. Dedicated IPs are included with their Pro and Premier Email API plans, while additional IPs are available for $30 per month. For optimal performance, SendGrid suggests using at least two dedicated IPs once your monthly email volume hits 200,000–300,000.

As SendGrid explains:

"Since you are the only one sending email over this IP, the sender reputation associated with this IP is determined purely by your sending practices."

Building and maintaining a dedicated IP’s reputation requires consistent and thoughtful email practices.

SMTP2GO Email Delivery

SMTP2GO simplifies access to dedicated IPs. All plans supporting 100,000 emails per month or more include one dedicated IP, and additional IPs can be added for $19 each per month. SMTP2GO recommends sending at least 5,000 emails per day, three or more days a week, to maintain a strong dedicated IP reputation. Plus, they handle reverse DNS setup automatically, reducing technical overhead.

SMTP2GO highlights the value of dedicated IPs, stating:

"Having a dedicated IP address in your SMTP2GO account means that all of your emails are sent out from an IP address that is only used by your own account. The reputation of this IP address is solely determined by the email that you send."

Delivery Comparison Table

Both providers offer strong email delivery solutions, but their approaches cater to different needs. SendGrid is ideal for high-volume senders who prioritize robust IP management, while SMTP2GO provides a user-friendly option with automated technical features. These distinctions set the stage for further evaluation in the next section.

Best Use Cases for Each Provider

When deciding between SendGrid and SMTP2GO for your Groupmail campaigns, your choice will largely depend on your goals, budget, and technical preferences. Both providers integrate effortlessly with Groupmail, but each shines in different scenarios.

When SendGrid Works Best

If you're managing high-volume campaigns and need enterprise-level features, SendGrid is your go-to option. It’s particularly suited for campaigns exceeding 100,000 emails per month, backed by robust infrastructure that sends over 148 billion emails monthly. With a 99% deliverability rate and a median delivery speed of just 1.9 seconds, SendGrid ensures your emails reach recipients quickly and reliably.

For enterprise users, SendGrid offers advanced analytics and automation tools. When combined with Groupmail’s drag-and-drop builder, it becomes a powerful tool for creating intricate email workflows.

Technical teams will also appreciate SendGrid’s flexibility. Features like custom pricing for high-volume campaigns and tools to safeguard sender reputation make it an excellent choice for businesses handling complex email operations.

When SMTP2GO Works Best

SMTP2GO is a better fit for users who are budget-conscious or sending smaller volumes of emails. With pricing starting at $15 per month - lower than SendGrid’s $19.95 starting tier - it provides excellent value. It also earns higher ratings for affordability, scoring 4.7/5 compared to SendGrid’s 4.0/5.

Small and medium-sized businesses often favor SMTP2GO for its simplicity. With ease-of-use ratings of 4.8/5 compared to SendGrid’s 4.1/5, it’s ideal for teams that want to focus on crafting engaging emails in Groupmail without needing to manage complex technical setups.

Customer support is another area where SMTP2GO excels, earning a 4.8/5 rating versus SendGrid’s 3.8/5. Users frequently praise its responsive and personable support team, which ensures smooth integration with Groupmail.

For businesses that prioritize straightforward functionality over advanced features, SMTP2GO delivers reliable email delivery with an easy setup process. While it may lack some of SendGrid’s enterprise-level tools, it effectively handles the core tasks most businesses need.

Final Recommendations

Your decision ultimately hinges on your business needs when integrating with Groupmail.

Go with SMTP2GO if you're looking for simplicity and affordability. This option works best for small to medium-sized businesses that prioritize ease of use and budget-conscious solutions. Users have praised its straightforward setup and cost structure. As John M, a CEO, noted, "Simplicity and they do not charge me for each SMTP user is a huge plus".

Technical expertise matters too. SMTP2GO is ideal for teams that want to focus on creating content without getting bogged down in technical details. Meanwhile, SendGrid is a better match for organizations equipped to fully utilize its advanced features and capabilities.

How do SendGrid and SMTP2GO compare in terms of setup and ease of use with Groupmail?

Both SendGrid and SMTP2GO are easy-to-use options for integrating with Groupmail, but their setup processes have some differences.

SendGrid gives you the flexibility to configure your account using either an API key or SMTP relay. To get started, you’ll need to create an account, generate an API key, and input the necessary details into Groupmail. This dual option makes it a suitable choice for users who like having both API and SMTP configuration options.

SMTP2GO, however, focuses solely on SMTP setup. Once you sign up, you’ll follow a straightforward process to connect their SMTP server with Groupmail. This approach is perfect for those who prefer a more traditional SMTP configuration.

Both services provide detailed, step-by-step guides, making them accessible to users with different levels of technical know-how. Since Groupmail supports both seamlessly, the decision comes down to your preferred setup method and what feels most comfortable for you.

Server locations and deliverability rates are critical factors when choosing between SendGrid and SMTP2GO for global email campaigns. SMTP2GO stands out with its extensive global server network, which not only speeds up email delivery but also minimizes the chances of emails being flagged by regional spam filters. With a deliverability rate of around 95.5%, it outperforms SendGrid, which has a deliverability rate of 82.0%, making it a more reliable option for campaigns that target diverse international audiences.

If achieving high deliverability and performance across global regions is your main goal, SMTP2GO is likely the stronger choice. That said, both services integrate seamlessly with Groupmail and can effectively support your campaigns based on your specific requirements.
