Start sending in minutes: With API libraries for pretty much every programming language you can think of, Postmark fits seamlessly into any stack. Stellar deliverability (without paying for a dedicated IP): You might say that Postmark has serious street cred with inbox providers. That's because we vet every new sender carefully, help you follow deliverability best practices, and never, ever let spammers use Postmark.

Easy Web UI and Reliable Transactional Email That Still Delivers **Rating:** 4.0/5.0 stars **Reviewed by:** Bryan M. | Product Director, Small-Business (50 or fewer emp.) **Reviewed Date:** April 29, 2026 **What do you like best about ActiveCampaign Postmark?** Easy web UI and reliable transactional email sending in comparison to the competition **What do you dislike about ActiveCampaign Postmark?** I fear that pricing will increase and service will get worse. While we were also an ActiveCampaign customer for 4~ years, we had to switch away from them because of service and pricing. While Postmark has been acquired by then and pricing had changed slightly since, it is still serving us well and I hope that it continues to. **What problems is ActiveCampaign Postmark solving and how is that benefiting you?** Postmark helps us send transaction emails to our users ### 2.

The Most Seamless & User-friendly Transactional Email delivery system for TruckX **Rating:** 4.0/5.0 stars **Reviewed by:** Ramesh K. | Associate Product Manager, Mid-Market (51-1000 emp.) **Reviewed Date:** July 23, 2024 **What do you like best about ActiveCampaign Postmark?** Email delivery and trust with our customers is our first priority at www.TruckX.com, so Postmark is our go-to for Email APIs because automated emails can be created and managed smoothly. **What do you dislike about ActiveCampaign Postmark?** Their analytics could be even more detailed in examining how the data performs. **What problems is ActiveCampaign Postmark solving and how is that benefiting you?** By ensuring that we deliver all www.TruckX.com ’s customer-facing transactional emails without delay, Postmark helps us ensure that our customers are happy and our operations are running smoothly. It has helped us become one of the best ELD brands for owner-operators and mid-sized fleets ### 4. Speed at a low price **Rating:** 4.0/5.0 stars **Reviewed by:** Ange B. | software engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** March 07, 2023 **What do you like best about ActiveCampaign Postmark?** I really appreciate the speed with which I receive emails. It's very important to me that customers receive emails on time because otherwise we can miss out on some business. **What do you dislike about ActiveCampaign Postmark?** I don't like the fact that sometimes Mustachio, which is the language used to write emails, is a bit old-fashioned and I have to find other ways to do things that could be done in a more simple way. **What problems is ActiveCampaign Postmark solving and how is that benefiting you?** Postmark helps me send emails to my customers and retrieve data on email opens. This allows me to have complete control and visibility over the email communications sent. ### 5. Definitely worth trying for your company - better than other options! **Rating:** 4.0/5.0 stars **Reviewed by:** Carney C. | Senior Web Designer, Mid-Market (51-1000 emp.) **Reviewed Date:** October 14, 2020 **What do you like best about ActiveCampaign Postmark?** Postmark is a really great service and gets the job done when delivering emails to our recipients. There are almost never any hiccups (i.e. emails getting blocked like some other delivery services). We're better able to provide website maintenance and hosting PLUS email delivery services, which is a great one-stop shop feature for clients. Some advice I would give to those on the fence is trying the free trial of Postmark to see if it's a good fit for your company. **What do you dislike about ActiveCampaign Postmark?** The price isn't as competitive as other options, which can sometimes be an issue dealing with clients. The training opportunities are also minimal if you don't know where to start, which can sometimes be an issue. The biggest dislike from a technical standpoint is there isn't an archiving option. Some clients like this feature when working with us, so that's one thing that can have us looking at other transactional email services. **Recommendations to others considering ActiveCampaign Postmark:** I would recommend the free trial to those considering Postmark. It's just slightly above average pricing, but is also a better option than the competitors, so overall I would recommend! **What problems is ActiveCampaign Postmark solving and how is that benefiting you?** We're able to use just Postmark in-house to manage transactional emails, which is a great benefit because when we need to look up something, we don't have to search through individual emails. If something were to go wrong, we can simply check with Postmark. As for our clients, we can use Postmark to deliver all the necessary emails almost always without fail, so this gives us credibility to get the job done when we say we can manage their email services. ### 6. Excellent service, premium price **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Small-Business (50 or fewer emp.) **Reviewed Date:** December 31, 2018 **What do you like best about ActiveCampaign Postmark?** The focus on transactional-only email and high deliverability is awesome; most small senders don't have the volume to justify the dedicated IPs every other transactional email provider seems to be pushing. The UI is nice. Documentation is good and API is easy to use. No complaints. **What do you dislike about ActiveCampaign Postmark?** The price is high and there's no free starter/low-volume plan. If slightly better deliverability is not critical for your use case, look elsewhere for more competitively priced solutions. **Recommendations to others considering ActiveCampaign Postmark:** If you're not price sensitive and you're looking for something simple with good support that just works, Postmark is a great choice. **What problems is ActiveCampaign Postmark solving and how is that benefiting you?** Sending transactional email (password resets, email verifications, etc.) ### 7. A clean simple api **Rating:** 3.5/5.0 stars **Reviewed by:** John P. | Software Engineer II, Financial Services, Mid-Market (51-1000 emp.) **Reviewed Date:** November 29, 2015 **What do you like best about ActiveCampaign Postmark?** Postmark has been simple and reliable in the 2+ years I've used them. Their API has a fast response time and their batch send calls has been helpful in maintaining a quick response time on our service. They've also been generous in giving us free credits from time to time. They provide webhooks for events you are interested in e.g. bounced emails, spam reports. Their documentation is extensive and comprehensive and also includes libraries for several languages (we use them with python and php). **What do you dislike about ActiveCampaign Postmark?** Some of the new features Postmark has added aren't as simple as their first product, especially the email templates. Their admin interface also is weird in that it only lets you look at 30 day periods for statistics (we track our own analytics so it's less of an issue for us). **Recommendations to others considering ActiveCampaign Postmark:** Postmark quickly and effectively help us getting transactional email up for our service. We've evaluated switching to Mailgun (since we get it for free) however right now postmark seems to have the simpler API. **What problems is ActiveCampaign Postmark solving and how is that benefiting you?** Postmark helped us quickly and effectively add an outside transactional email provider instead of sending SMTP emails. It's also helped ensure that our app stays quick when we were originally directly calling it from the application thread. We've had no problem with getting marked as spam or deliverability and their open tracking by email client has been helpful. We've sent 200,000+ emails with postmark so far. ## ActiveCampaign Postmark Discussions - [What is ActiveCampaign Postmark used for?](https://www.g2.com/discussions/what-is-activecampaign-postmark-used-for) - [How do you use postmark?](https://www.g2.com/discussions/how-do-you-use-postmark) - [What is Postmark API?](https://www.g2.com/discussions/what-is-postmark-api) - [What is postmark email service?](https://www.g2.com/discussions/what-is-postmark-email-service) - [What is postmark tool?](https://www.g2.com/discussions/what-is-postmark-tool) - [View ActiveCampaign Postmark pricing details and edition comparison](https://www.g2.com/products/activecampaign-postmark/reviews?filters%5Bnps_score%5D%5B%5D=4§ion=pricing&secure%5Bexpires_at%5D=2026-08-12+11%3A46%3A45+-0500&secure%5Bsession_id%5D=cc22a5db-2e35-4898-8d4f-93c2b85a9500&secure%5Btoken%5D=ebfeaa7267044e4b0f1e7ecdb36866b26097fd49212d02cddbe70289ee6526f9&format=llm_user) ## ActiveCampaign Postmark Features **Administration** - Template Creation - Preset Template Availability - Detailed Server Logs - Alerts/Notifications - Drip Campaigns - Customer Segmentation **Integrations** - Webhooks - Event Tracking API - Mail Send API - Spam Filter Testing - Activity Dashboard - Activity Tracking - A/B Testing **Platform** - Multiple Domains - Dedicated IP - Documentation - Sender Reputation Management - Tracking & Reporting - Enterprise Scalability - Performance and Reliability - Workflow Management - List Management - Template Management - Email Management - Subscription Management - Click Tracking **Additional Functionality** - Third-Party Integrations - Customizable Branding - Email Monitoring - Generative AI - Mobile Access - WYSIWYG Editor - Real-Time Data - Unsubscribe Database - AI Copilot - Drag & Drop - Geolocation - Event Triggered Actions - Simple Mail Transfer Protocol (SMTP) - Contact Database - Campaign Analytics - SMS Messaging - Customizable Forms - Autoresponders - Email Marketing - Message Personalization - Reporting/Analytics - Dynamic Content - Customizable Fields - Campaign Scheduling - Email Distribution ## Top ActiveCampaign Postmark Alternatives - [Brevo Marketing Platform](https://www.g2.com/products/brevo-marketing-platform/reviews) - 4.5/5.0 (2,481 reviews) - [Twilio SendGrid Email API](https://www.g2.com/products/twilio-sendgrid-email-api/reviews) - 4.0/5.0 (358 reviews) - [Mailgun](https://www.g2.com/products/mailgun/reviews) - 4.2/5.0 (314 reviews)
