Overview
EmailIt and Mailgun serve different needs in the email space. EmailIt is a budget pay-per-email delivery service. Mailgun is a developer-focused email API with validation tools.
The choice depends on what you need: cheapest per-email pricing (EmailIt) or powerful api (Mailgun). For SaaS businesses specifically, Sequenzy offers purpose-built features that neither tool provides.
Pricing reality
- EmailIt: ~$1-2/10k emails - Pay-per-email, no subscription. SMTP and API.
- Mailgun: $35/month (50k) - Developer-focused API. Email validation included.
- Sequenzy: $99/month for 120,000 emails, unlimited subscribers, fully managed. See pricing.
Review signals
The EmailIt reviews on this page support low-volume, low-complexity sending. One reviewer says Mailgun was overkill for 5,000 monthly notification emails and EmailIt handled the same job for a fraction of the cost.
The caution signal is production tooling. Another reviewer says EmailIt is refreshing but misses Mailgun's delivery logs and email validation for serious production email.
Mailgun's reviews support the mature developer-platform argument: validation, inbound routing, and a strong API are valued. The negative review points to post-acquisition price increases and a reduced free tier as reasons teams evaluate simpler alternatives.

Why Sequenzy for SaaS
If you are building a SaaS product, Sequenzy offers what neither EmailIt nor Mailgun provides: native Stripe integration for billing-based automation, AI sequences that generate onboarding and retention emails, and unified transactional + marketing email in one platform. Check our pricing page for details.
Delivery Speed and Reliability
For transactional email, delivery speed is non-negotiable. Receipts, password resets, and verification codes need to arrive in seconds. Both Emailit and Mailgun prioritize fast delivery, but their approaches differ in infrastructure and routing.
Transactional email reliability involves more than just speed. It requires consistent inbox placement, proper authentication, and monitoring. Compare how each platform handles DKIM, SPF, and DMARC setup, and which provides better tools for ongoing email deliverability monitoring.
API Design and Developer Experience
Emailit and Mailgun both target developers, but with different philosophies. The quality of API documentation, SDK support, and error handling directly impacts how quickly your team can integrate and how much ongoing maintenance is needed.
Developer experience goes beyond the API itself. Consider webhook support for tracking delivery events, sandbox environments for testing, and how each platform handles rate limiting and error recovery. These details matter when your application depends on email delivery.
Scaling and Cost at Volume
Email costs become significant at scale. What starts as a few hundred emails per day can grow to millions. Understanding how Emailit and Mailgun price at different volume tiers helps you plan for growth without budget surprises.
Beyond per-email pricing, consider dedicated IP costs, email validation charges, and support tier pricing. Some platforms offer volume discounts that significantly change the economics at higher sending volumes. For SaaS companies needing both transactional and marketing email, explore Sequenzy's unified approach.
The Sinch Acquisition Impact
Mailgun was acquired by Sinch in 2021, and the impact on pricing has been significant. The previously generous free tier (10,000 emails/month for three months) was reduced, and paid plan prices increased. Long-time Mailgun users frequently cite the acquisition as the moment they started evaluating alternatives.
EmailIt benefits from this market shift by offering a simpler, cheaper alternative for teams that do not need Mailgun's full feature set. If you used Mailgun primarily for basic SMTP relay and REST API sending, EmailIt provides the same core functionality at lower cost without the corporate acquisition concerns.
However, Sinch also brought resources that improved Mailgun in some areas. Infrastructure investment, expanded global presence, and multi-channel capabilities through the broader Sinch platform. For teams that value organizational stability and investment, Sinch's backing provides more confidence than EmailIt's smaller independent operation. The question is whether you are paying for features and stability you actually use.
The Email Validation Divide
Mailgun includes email validation as a core feature, allowing you to verify email addresses before sending. This protects your sender reputation by preventing bounces from invalid addresses. Email validation is particularly important for applications that accept user-submitted email addresses -- registration forms, contact forms, and user invitations.
EmailIt has no email validation capability. If an address bounces, you discover it after the fact through delivery failure notifications. For applications where email addresses come from trusted sources (internal systems, authenticated users), this is rarely a problem. For applications accepting public input, the lack of validation creates deliverability risk.
The validation gap matters most at scale. A few bounces from bad addresses are manageable. Hundreds or thousands of bounces can damage your sender reputation and affect delivery to legitimate addresses. If your application processes user-submitted emails at volume, Mailgun's validation provides meaningful protection that EmailIt simply cannot offer.
The SaaS Integration Question
Both EmailIt and Mailgun are general-purpose email APIs without SaaS-specific features. Mailgun's inbound routing is useful for processing replies, but neither platform understands subscription billing, trial periods, or customer lifecycle stages. Building SaaS email automation on either requires custom webhook processing and workflow logic in your application code.
Sequenzy eliminates this custom work with native Stripe integration that triggers emails from billing events automatically. Combined with AI-powered sequences for onboarding and retention, and unified transactional plus marketing email at $49/month, it provides the SaaS-specific automation that neither EmailIt's simplicity nor Mailgun's developer tools can match.
Use-case matchups
| Use case | Better fit | Why |
|---|---|---|
| Lowest-cost simple transactional email | EmailIt | EmailIt is better when the team only needs basic API/SMTP sending and wants to avoid a monthly platform minimum. |
| Mature developer email API | Mailgun | Mailgun is stronger when validation, inbound routing, EU region support, logs, SDKs, and dedicated IPs matter. |
| MVP or side-project notifications | EmailIt | EmailIt is easier when volume is low and advanced troubleshooting tools would sit unused. |
| User-submitted email addresses at scale | Mailgun | Mailgun's email validation helps protect sender reputation before bad addresses cause bounces. |
| SaaS lifecycle automation | Sequenzy | Sequenzy is better when Stripe events, transactional email, and lifecycle campaigns need one SaaS-focused workspace. |
| Reply processing and inbound workflows | Mailgun | Mailgun is the better fit when inbound routing is part of the product experience. |
Best Fit by Developer Email Depth
Best cheap email API for basic transactional sending
EmailIt is the better fit when the product needs simple notification, password-reset, receipt, or alert emails without validation, inbound routing, dedicated IPs, or advanced logs. It suits teams that can keep templates and monitoring in their own application and want a lightweight pay-per-email sender. The value is minimal platform overhead, not a full developer email toolkit.
Best developer email API for validation and inbound routes
Mailgun is stronger when email is part of the product workflow, not just outbound delivery. Choose it for inbound route processing, reply handling, email validation, EU-region needs, dedicated IPs, SDKs, and more mature troubleshooting tools. It is the better fit when user-submitted addresses, webhook logic, and deliverability operations carry meaningful product or revenue risk.
Best SaaS email platform for Stripe-triggered lifecycle
Sequenzy is the better fit when the team is building subscription lifecycle email rather than raw sending infrastructure. SaaS products need trial onboarding, billing reminders, receipts, failed-payment recovery, upgrade prompts, and lifecycle campaigns connected to customer state. That business logic is not native to either EmailIt or Mailgun, so Sequenzy removes custom workflow code.
Migration checklist
| Workstream | What to verify |
|---|---|
| Sending setup | Move domains, sender identities, SMTP/API credentials, webhooks, suppression lists, and template references. |
| Inbound and validation | If moving to Mailgun, rebuild routes, reply processing, validation calls, and region-specific settings. |
| Monitoring | Recreate logs, event webhooks, bounce handling, complaint processing, and reputation alerts. |
| SaaS lifecycle | If moving to Sequenzy, map Stripe events, subscribers, transactional templates, and marketing campaigns into one flow. |
| Production cutover | Test password resets, receipts, inbound replies if used, bounces, unsubscribes, and DNS before raising traffic. |
Decision checklist
Does the application need email validation before sending to user-submitted addresses?
Are inbound routes, EU region support, logs, SDKs, or dedicated IPs required?
Is Mailgun's $35/month floor justified by operational tooling, or is EmailIt enough?
How much does the Sinch-era pricing/support change affect the buying decision?
Would SaaS billing events and lifecycle campaigns make Sequenzy a better fit than either API?
Decide whether the destination should optimize for raw cost, mature developer tooling, or SaaS lifecycle automation.
Export verified domains, sender identities, SMTP/API keys, templates, routes, inbound parsing rules, validation data, suppressions, webhooks, and delivery logs.
If moving to Mailgun, configure domains, routes, validation, EU/US region needs, webhooks, logs, and dedicated IP requirements before switching traffic.
If moving to EmailIt, identify which Mailgun validation, inbound routes, logs, SDKs, EU region, and dedicated IP workflows need replacement elsewhere.
Rebuild critical transactional templates first: verification, password reset, invite, receipt, invoice, billing, alert, and notification emails.
Reconnect API/SMTP calls, webhooks, bounce handling, complaint handling, inbound routes, alerts, analytics, and suppression syncing.
Authenticate SPF, DKIM, and DMARC, then test one API send, one SMTP send, one webhook event, and one inbound route if used before full migration.
Preserve historical validation, delivery, inbound, bounce, complaint, cost, and support reports so the team can compare low-cost simplicity against mature API tooling.
