Overview
EmailIt and MailerSend serve different needs in the email space. EmailIt is a budget pay-per-email delivery service. MailerSend is a clean transactional email service with SMS support.
The choice depends on what you need: cheapest per-email pricing (EmailIt) or clean interface (MailerSend). 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.
- MailerSend: Free (3k/mo), then $28/mo - From MailerLite team. Email verification + SMS.
- Sequenzy: $99/month for 120,000 emails, unlimited subscribers, fully managed. See pricing.
Review signals
The EmailIt reviews on this page support the ultra-simple transactional use case. One reviewer says EmailIt costs pennies for 1,500 monthly transactional emails and was simpler to integrate than MailerSend.
The negative EmailIt signal is adjacent tooling. Another reviewer moved to MailerSend when they needed email verification and SMS for two-factor authentication.
MailerSend's reviews reinforce the free-tier and operational-tooling advantages: reviewers call out the 3,000-email free tier, email verification, delivery analytics, and inbound parsing. The limitation is template flexibility, not basic sending.

Why Sequenzy for SaaS
If you are building a SaaS product, Sequenzy offers what neither EmailIt nor MailerSend 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 MailerSend 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 MailerSend 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 MailerSend 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 MailerLite Family Advantage
MailerSend benefits from being built by the team behind MailerLite, one of the most respected email marketing platforms for small businesses. This lineage brings infrastructure experience, deliverability knowledge, and a proven track record of building reliable email products. EmailIt is an independent service without the same organizational depth behind it.
The MailerLite connection also creates a natural upgrade path. Teams can use MailerSend for transactional email and MailerLite for marketing, with both products sharing domain verification and account management. This two-product approach from one company is smoother than combining EmailIt with a completely separate marketing platform.
However, the MailerLite relationship also means MailerSend is somewhat dependent on its parent company's priorities. Feature development, infrastructure investment, and support resources are shared across products. EmailIt, as a focused single-product company, might iterate faster on its core transactional sending capability without competing for resources.
The Free Tier Comparison
MailerSend's free tier of 3,000 emails per month is genuinely useful for startups and side projects. It covers a meaningful amount of transactional email without any cost, letting teams validate their integration before committing to paid plans. EmailIt has no free tier -- you pay per email from the first send.
For early-stage projects, MailerSend's free tier provides a significant advantage. You can build and test your entire transactional email integration, including webhooks and delivery tracking, without spending anything. This reduces the risk of choosing the wrong platform because there is no cost to trying it.
Once you exceed 3,000 monthly emails, the cost comparison shifts. MailerSend's paid plans start at $28/month, which may or may not be cheaper than EmailIt's per-email pricing depending on your volume. Calculate your expected monthly sending to determine which model provides better value at your scale.
Beyond Transactional Sending
Both EmailIt and MailerSend focus on transactional email, but neither provides the marketing automation or subscription lifecycle management that SaaS businesses need. Password resets and order confirmations are table stakes -- the competitive advantage comes from automated onboarding sequences, churn prevention workflows, and billing-aware email campaigns.
Sequenzy provides this higher-level automation with native Stripe integration, AI-generated sequences, and unified transactional plus marketing email. At $49/month, it costs more than either transactional-focused option but eliminates the need for a separate marketing platform alongside your transactional sender. See pricing for details.
Use-case matchups
| Use case | Better fit | Why |
|---|---|---|
| Lowest-cost simple transactional email | EmailIt | EmailIt is better when the team needs basic API/SMTP sending and wants the lowest possible ongoing cost. |
| Polished transactional dashboard | MailerSend | MailerSend is stronger when the team wants a clean UI, activity tracking, webhooks, and easier operational monitoring. |
| Early project under 3k emails/month | MailerSend | MailerSend's free tier is useful for startups and side projects validating transactional email. |
| Existing SMTP app with minimal needs | EmailIt | EmailIt is straightforward when the application already sends through SMTP and extras like SMS or verification are unnecessary. |
| SaaS lifecycle automation | Sequenzy | Sequenzy is better when Stripe events, transactional email, and lifecycle campaigns need one SaaS-focused workspace. |
| Email verification, SMS, or inbound parsing | MailerSend | MailerSend includes adjacent tools that EmailIt does not provide. |
Best Fit by Transactional Operations
Best low-cost transactional email tool for simple apps
EmailIt is the better fit when the application only needs dependable SMTP or API sending and the team wants to keep recurring platform cost close to usage. It suits side projects, MVPs, internal tools, and small SaaS apps where templates live in code, volume is modest, and advanced dashboard workflows would sit unused. The buyer should be comfortable owning logs, alerts, and operational checks.
Best transactional email platform for teams that need a polished dashboard
MailerSend is stronger when non-developers need visibility into activity, templates, webhooks, inbound parsing, verification, or SMS-adjacent workflows. Choose it when the team wants a more complete transactional operations layer and a free tier before paid usage. It is especially useful when support, product, and engineering all need to inspect email status without pulling raw logs.
Best SaaS email platform for billing and lifecycle automation
Sequenzy is the better fit when transactional sending is only one part of the email system. SaaS teams need Stripe-triggered lifecycle email, onboarding, receipts, failed-payment recovery, renewal reminders, product campaigns, and transactional routes together. That makes Sequenzy more relevant when business events should trigger email automatically instead of being coded around a generic sender.
Migration checklist
| Workstream | What to verify |
|---|---|
| Transactional routes | Move SMTP/API credentials, sender identities, templates, webhook endpoints, and bounce/complaint handling. |
| Operations | Recreate activity monitoring, alerting, message search, logs, and support workflows in the target platform. |
| Adjacent features | If moving to MailerSend, map verification, inbound parsing, SMS, and template ownership; if moving to EmailIt, replace those elsewhere. |
| SaaS lifecycle | If simplifying to Sequenzy, map transactional events, Stripe triggers, subscriber data, and campaign segments together. |
| Cutover | Reverify SPF, DKIM, DMARC, tracking domains, suppression behavior, and one password-reset or receipt flow before switching production traffic. |
Decision checklist
Is the project under MailerSend's free 3,000-email monthly tier?
Does the team need email verification, SMS, inbound parsing, or a polished monitoring dashboard?
Would EmailIt's simpler API and pay-per-email model be enough for the current transactional workload?
Are templates owned in code, or does the team need dashboard-based template management?
Would SaaS lifecycle automation and unified marketing plus transactional email justify Sequenzy instead?
Decide whether the destination should optimize for raw cost, transactional tooling polish, or SaaS lifecycle automation.
Export verified domains, sender identities, SMTP/API keys, templates, webhooks, inbound routes, SMS settings, email verification data, suppressions, and delivery reports.
If moving to MailerSend, configure domains, webhooks, inbound parsing, SMS, email verification, and activity monitoring before switching production traffic.
If moving to EmailIt, identify which MailerSend verification, SMS, inbound parsing, dashboard, and webhook 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, alerts, analytics, inbound routes, and suppression syncing.
Authenticate SPF, DKIM, and DMARC, then test one API send, one SMTP send, one webhook event, and one bounce path before full migration.
Preserve historical delivery, verification, SMS, inbound, webhook, cost, and support reports so the team can compare raw sending cost against operational tooling.
