Overview
EmailIt and SMTP2GO serve different needs in the email space. EmailIt is a budget pay-per-email delivery service. SMTP2GO is a simple SMTP relay with good support.
The choice depends on what you need: cheapest per-email pricing (EmailIt) or simple setup (SMTP2GO). 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.
- SMTP2GO: $10/month - SMTP relay focus. Good support. Detailed analytics.
- Sequenzy: $49/month for 120,000 emails, unlimited subscribers, fully managed. See pricing.
Review signals
The EmailIt reviews on this page support tiny-volume sending. One reviewer says SMTP2GO's $10/month minimum does not make sense for 500 monthly emails.
The negative EmailIt review shows the support and diagnostics gap: when a batch bounced, the team lacked the tools to diagnose the problem and moved to SMTP2GO for reporting and suppression management.
SMTP2GO's reviews reinforce the operational value: responsive support, detailed reporting, reliable setup, and automatic suppression management. That makes the $10/month minimum easier to justify when delivery problems would be costly.

Why Sequenzy for SaaS
If you are building a SaaS product, Sequenzy offers what neither EmailIt nor SMTP2GO 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 SMTP2GO 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 SMTP2GO 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 SMTP2GO 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.
Use-case matchups
| Use case | Better fit | Why |
|---|---|---|
| Lowest-cost low-volume sending | EmailIt | EmailIt's pay-per-email model is best when monthly volume is tiny and support needs are low. |
| Reliable SMTP relay with support | SMTP2GO | SMTP2GO is stronger when the team values setup help, diagnostics, suppression management, and delivery reporting. |
| Simple app notifications | Tie | Both can send basic transactional emails through SMTP/API when the team handles template and workflow logic elsewhere. |
| Deliverability troubleshooting | SMTP2GO | SMTP2GO provides better support and analytics for diagnosing bounces, deferrals, and reputation issues. |
| SaaS marketing plus transactional email | Sequenzy | Sequenzy is better when campaigns, transactional messages, and Stripe-triggered lifecycle automation need one workspace. |
| Developer-controlled minimal stack | EmailIt | EmailIt is the lighter option when developers want delivery only and do not need operations tooling. |
The Support Quality Difference
SMTP2GO has built a genuine reputation for responsive, knowledgeable customer support. Their team understands email delivery at a technical level and provides actionable help with authentication issues, deliverability problems, and configuration questions. EmailIt, as a smaller operation, cannot match this level of support infrastructure.
For teams without dedicated email operations expertise, good support is worth more than the price difference suggests. A single deliverability issue that takes days to diagnose without help can cost far more in lost emails than SMTP2GO's $10 monthly subscription. EmailIt's lower cost assumes you can troubleshoot problems independently.
That said, both platforms focus on SMTP relay and delivery -- neither offers marketing email support, subscriber strategy guidance, or automation help. SaaS companies needing guidance on onboarding sequences, retention campaigns, or lifecycle email architecture need a platform built for that purpose.
The Bounce Management Factor
SMTP2GO's automatic suppression management handles bounced addresses without manual intervention. When an email bounces, SMTP2GO suppresses future sends to that address, protecting your sender reputation. EmailIt provides minimal bounce handling, leaving reputation management largely to you.
Bounce management matters more than most teams realize until they hit problems. Repeatedly sending to bounced addresses damages your domain reputation with ISPs, which can cause deliverable emails to start landing in spam. SMTP2GO's automated approach prevents this spiral. EmailIt users need to build their own suppression logic or risk reputation damage.
For SaaS businesses, bounces often correlate with business events -- employees leaving companies, free trial users using throwaway addresses, or churned customers abandoning email accounts. Connecting bounce data to subscriber segments and Stripe subscription status provides context that pure SMTP relay services cannot offer.
The Analytics Visibility Gap
SMTP2GO provides detailed delivery analytics showing what happened to every email -- delivered, bounced, deferred, opened, clicked. This visibility helps identify problems before they become critical. EmailIt's reporting is minimal, giving you basic send confirmation without the granular tracking that informs optimization.
Detailed analytics become essential as sending volume grows. A subtle deliverability decline might show up as a gradual drop in open rates across certain ISPs. SMTP2GO's reporting can surface this trend. EmailIt users might not notice until delivery rates have significantly degraded.
However, both platforms limit analytics to delivery metrics. Neither tracks downstream business impact -- which emails drive signups, which campaigns generate revenue, or which transactional emails correlate with user retention. SaaS companies that need to connect email performance to business outcomes through subscriber activity tracking require a more complete platform.
Migration checklist
Decision checklist
Is monthly volume small enough that EmailIt's pay-per-email model clearly beats SMTP2GO's minimum?
Does the team need support help for authentication, bounces, deferrals, or reputation issues?
Is automatic suppression management required to protect sender reputation?
Would SMTP2GO's reporting reduce operational risk enough to justify the subscription?
Would SaaS lifecycle automation and unified marketing plus transactional email justify Sequenzy instead?
Decide whether support, reporting, and suppression management justify a monthly SMTP relay subscription.
Export verified domains, sender identities, SMTP/API credentials, templates, suppression lists, webhook endpoints, bounce logs, delivery reports, and dedicated IP settings.
If moving to SMTP2GO, map EmailIt API/SMTP calls, bounce handling, reporting needs, suppression behavior, and alerting into SMTP2GO's relay setup.
If moving to EmailIt, identify which SMTP2GO analytics, suppression rules, email tests, dedicated IP settings, and support workflows must be replaced.
Rebuild critical transactional templates first: verification, password reset, invite, receipt, invoice, billing, alert, and notification emails.
Reconnect SMTP/API calls, SDKs, webhooks, bounce handling, complaint handling, alerts, analytics exports, and monitoring.
Authenticate SPF, DKIM, and DMARC, then run seed tests plus a small production cohort before moving all transactional volume.
Preserve historical delivery, latency, bounce, complaint, cost, and support reports so the team can compare low cost against operational visibility.
