TL;DR
- Best for developer-grade transactional email at scale: Mailgun (GetApp 4.3/5 from 197 reviews, TrustRadius 9.1/10, 150,000+ customers including Lyft, Microsoft, and Wikipedia, enterprise API with email validation and deliverability tools)
- Best for AI-powered email building with forms, data, and automation: TinyEmails (visual drag-and-drop builder, AI content generation, drip sequences, natively connected to TinyForms, TinyTables, TinyWorkflows, and TinyAgents)
- Pricing: Mailgun starts at $35/mo for 50,000 emails (email only). TinyCommand starts free, paid from $19/mo for the entire platform.
- The core difference: Mailgun is an email API for developers who write code to send transactional emails. TinyEmails is a visual email builder for non-technical users who need email as part of a complete business automation platform. They serve different users solving different problems.

The real comparison: Mailgun at $35/month gives you transactional email sending. TinyCommand at $19/month gives you email building, sending, forms, database, workflow automation, and AI agents. Mailgun is cheaper per email at high volume but is email-only. TinyCommand is a complete platform.
"We used to run our lead enrichment and outreach through five different tools. With TinyCommand, it is just one flow."

Mailgun is one of the most trusted transactional email APIs in the world. Acquired by Sinch in 2021, it serves over 150,000 businesses including Lyft, Microsoft, Wikipedia, American Express, and Substack. Developers use Mailgun's RESTful API and SMTP relay to send password resets, order confirmations, notifications, and any programmatic email at scale. TrustRadius rates it 9.1 out of 10 from 66 reviews — one of the highest scores in the email infrastructure category.
TinyEmails is a completely different product. It is a visual email builder with AI-powered content generation, drag-and-drop design, merge fields from your database, and drip sequence automation. It exists as one product inside TinyCommand, natively connected to forms (TinyForms), databases (TinyTables), workflows (TinyWorkflows), and AI agents (TinyAgents). No API. No code. No HTML templates.
These tools exist in different categories. Mailgun is email infrastructure — the pipes that deliver emails. TinyEmails is email creation and marketing — the tool that designs, writes, and schedules emails. Some businesses need both. Most need one or the other.
Where Each Tool Wins
Where Mailgun wins
Email deliverability infrastructure. DKIM, SPF, dedicated IPs, IP warm-up, inbox placement testing, and ISP feedback loops. For teams sending millions of transactional emails daily, Mailgun's delivery infrastructure is enterprise-grade. TinyEmails does not offer dedicated IPs or deliverability testing tools.
Developer API. RESTful API with comprehensive documentation, SMTP relay, webhooks for delivery events (bounces, opens, clicks, spam complaints). Developers can integrate Mailgun into any application in minutes. Rated 9.1/10 on TrustRadius with praise for API reliability.
Email validation. Built-in API for verifying email addresses — syntax, MX records, disposable email detection, mailbox verification. Validate lists before sending to protect your sender reputation.
Enterprise scale. 150,000+ customers including Lyft, Microsoft, Wikipedia, and American Express. Processes billions of emails. Proven at volumes that most marketing platforms cannot handle.
Inbound email parsing. Receive emails programmatically — Mailgun can parse incoming emails and route them to your application via webhooks. Useful for support ticket systems and automated email processing.
Where TinyEmails wins
Visual email builder. Drag-and-drop editor with AI content generation. Design professional emails without writing HTML. Mailgun has no visual editor at all — you code every email or use a separate tool.
All-in-one platform. TinyEmails connects natively to TinyForms (data collection), TinyTables (contact database with 7 views), TinyWorkflows (automation across 100+ apps), and TinyAgents (AI agents). Mailgun is email sending only.
No code required. Marketers, founders, and non-technical team members can create and send email campaigns without touching code. Mailgun requires API integration or SMTP configuration — it is a developer tool.
AI-powered content. Describe what you want and TinyEmails generates email copy using AI. Write subject lines, body text, and CTAs with AI assistance. Mailgun has no content generation features.
Drip sequences. Build visual multi-step email sequences with time delays, conditions, and personalization. Mailgun's sequence capabilities require custom code through its API.
Cost efficiency. TinyCommand at $19/month includes email, forms, database, workflows, and AI. The equivalent Mailgun stack (Mailgun + form builder + database + automation tool + design tool) costs $100+/month.
Email infrastructure vs email marketing platform
Mailgun's strength is under the hood. Its API handles email delivery with features that marketers never see: DKIM signing, SPF alignment, bounce handling, feedback loops with ISPs, IP reputation management, inbox placement testing, and detailed delivery logs. When you send 100,000 transactional emails per day, these infrastructure details determine whether your emails reach the inbox or the spam folder.
The email validation API is another developer tool. Upload a list of email addresses and Mailgun checks each one for deliverability — syntax validation, MX record checks, disposable email detection, and mailbox verification. This is not a feature most marketing platforms offer natively.
But Mailgun has no visual email builder. No drag-and-drop editor. No AI content generation. No template library you can browse and customize. If you want to design an email, you write HTML or use a third-party tool and paste the code into Mailgun. GetApp reviewers consistently flag this: "Limited templates; requires HTML coding or third-party tools."
This is where TinyEmails fills a completely different need. You open TinyEmails, describe what you want, and the AI generates a first draft. You drag and drop blocks to customize the layout. You insert merge fields that pull data from TinyTables — {{first_name}}, {{company}}, {{last_purchase_date}}. You set up a drip sequence: send email 1 on day 0, email 2 on day 3 if no reply, email 3 on day 7. All visual. All connected to your data.
And because TinyEmails is part of TinyCommand, the email is just one step in a larger flow. A lead fills out a TinyForm → the data writes to TinyTables → TinyWorkflows enriches the record → TinyAgents scores the lead → TinyEmails sends a personalized sequence. One platform. One data layer. No API integration between separate tools.
Mailgun cannot do any of this without external tools. You need a form builder (Typeform, $29/mo), a database (Airtable, $20/mo), an automation tool (Zapier, $20/mo), and a design tool (Stripo or BEE, $15/mo) before you can create, personalize, and send a marketing email through Mailgun. The total stack cost exceeds $100/month — and you still need a developer to wire it together.
The one area where Mailgun is genuinely superior is deliverability at scale. Dedicated IPs, IP warm-up tools, inbox placement testing, and ISP feedback loops are enterprise email infrastructure features that TinyEmails does not offer. If you send millions of transactional emails daily and deliverability is your primary concern, Mailgun's infrastructure is purpose-built for it.
