If you're sending transactional or bulk email, like order confirmations, password resets, invoices, notifications, or newsletters, you need an SMTP relay or email API you can trust to land in the inbox, scale with your volume, and not eat your budget alive. SMTP2GO has built a solid reputation as a reliable transactional email service, and it's a common shortlist item for developers comparing SMTP providers.
But it isn't the only option, and for many teams it isn't the best-value one either. Elastic Email offers the same core building blocks - SMTP relay and a REST API for sending mail programmatically. But, it also includes email design tools, AI-assisted template creation, and white-label options that SMTP2GO simply doesn't offer at any price point. Add in pricing that stays meaningfully cheaper as your sending volume grows, and Elastic Email becomes a compelling alternative worth evaluating before you commit to a provider. This article compares Elastic Email's Email API plans against SMTP2GO's plans head-to-head: what each costs, what each includes, and where Elastic Email pulls ahead as an SMTP2GO alternative.
TL;DR - Elastic Email as an SMTP2GO Alternative
- Cheaper at the same volume. Elastic Email's Starter plan ($19/month) includes 50,000 emails/month. Matching that volume on SMTP2GO Starter costs $30/month.
- More free-tier volume. Elastic Email's free plan allows up to 3,000 emails/month. SMTP2GO's free plan caps out at 1,000 emails/month.
- Built-in email design, not just relay. Elastic Email includes a drag-and-drop Email Designer, a template gallery, and an AI Template Designer on every plan, including API plans. SMTP2GO has no equivalent design or content-generation tooling.
- White-label and reseller features. Elastic Email's Pro plan includes white-label SMTP and API, custom branded UI, and CNAME hosting, useful for agencies. SMTP2GO offers subaccounts but no comparable white-label branding.
- Both are reliable SMTP/API relays with SPF, DKIM, suppression management, and analytics, so switching doesn't mean giving up the fundamentals.
Pricing Comparison
Pricing is where the two providers diverge most. Below is a comparison using each provider's Email API/transactional plans as of July 2026:
Email sending limit |
SMTP2GO |
Elastic Email |
50,000 |
$30 (Starter) | $19 (Starter) $49 (Pro) |
100,000 |
$75 (Professional) | $29 (Starter) $59 (Pro) |
250,000 |
$170 (Professional) | $99 (Starter) $159 (Pro) |
500,000 |
$280 (Professional) | $169 (Starter) $199 (Pro) |
Starting at the 50,000-email tier onwards, Elastic Email proves to be significantly cheaper than SMTP2GO. Additionally, if your email sending volume exceeds 50,000, you need to upgrade from Starter to Professional when using SMTP2GO. With Elastic Email, your plan does not depend on the amount of emails you send, but the feature set you need. That is why every email sending limit is available for the Starter and Pro plan.
Email design tools included into API plans
SMTP2GO is a pure SMTP relay and API. It moves your mail reliably but gives you no way to build the email itself beyond raw HTML you supply. Elastic Email's Email API plans, by contrast, include a drag-and-drop Email Designer, a gallery of pre-built templates, and responsive, mobile-friendly layouts, even on plans marketed for developers and transactional sending. If your team occasionally needs to spin up a templated email without hand-coding HTML, this is a tool SMTP2GO doesn't have at all.
Elastic Email adds an AI Template Designer to every plan - 10 prompts/month on Free, 40 prompts/month on Starter, up to 100/month on Pro - letting you generate email layouts and copy from a prompt instead of building from scratch. SMTP2GO has no AI content or template generation feature in any plan, since it isn't built as a design tool. For teams that want to move fast on campaign or notification design without a dedicated designer, this is a meaningful gap in SMTP2GO's offering.
Higher free-plan sending volume
SMTP2GO offers a plan for testing and sending low volumes giving 1,000 emails/month with the 200-email daily limit. You also get 5 days of email reporting and ticket support. In Elastic Email, email plan includes all the Starter plan features and 3,000 emails/month with the 100-email daily cap. Customer support is provided from day one and is available 24/7 for all users via email and live chat.
White-label and reseller capabilities
Elastic Email's Pro plan includes features built specifically for agencies and platforms that want to resell email sending under their own brand: white-label SMTP, white-label HTTP API, a UI hosted on your own domain, and easy CNAME setup. SMTP2GO offers subaccounts for managing multiple clients internally, but nothing in its published feature set lets you rebrand the platform itself for resale. If white-labeling is on your roadmap, Elastic Email supports that use case natively, while SMTP2GO doesn't.
More granular suppression management, plus built-in email verification
Both providers include suppression list management as a core feature, and both handle SPF, DKIM, and bounce/unsubscribe handling as standard. Where Elastic Email stands out is granularity: its suppression tooling includes per-contact status tracking, exportable suppression list data, multiple unsubscribe methods, and unsubscribe-reason insights, rather than a single blanket suppression list. Elastic Email also includes single and bulk email verification directly into its API plans, so you can clean a list before sending without a separate tool.

Conclusion
SMTP2GO is a dependable SMTP relay with a long track record, and if all you need is bare mail delivery, it will get the job done. But "dependable" isn't the same as "best value," and it isn't the same as "full-featured." Elastic Email matches SMTP2GO on the fundamentals - SMTP relay, API sending, authentication, deliverability tooling. But, it costs meaningfully less at the volumes most growing businesses actually send, and while including email design, AI-assisted template creation, and white-label options that simply aren't part of SMTP2GO's product at any price.
If you're comparing SMTP2GO alternatives because your email costs are creeping up as you scale, or because you want more than a bare relay, Elastic Email is worth a serious look. And, with a free plan and no credit card required to start, testing it against your current setup costs nothing but a little setup time.
FAQ
Is Elastic Email cheaper than SMTP2GO?
At matched sending volumes, generally yes. Elastic Email's $19/month Starter plan includes 50,000 emails/month, while reaching the same volume on SMTP2GO costs roughly $30 (Starter plus overage) to $75/month (Professional plan). SMTP2GO's absolute entry price ($10/month) is lower, but it covers only 10,000 emails/month, so the comparison depends on your actual sending volume.
Does Elastic Email offer a free plan like SMTP2GO?
Yes. Elastic Email's free plan allows up to 3,000 emails/month (100/day) with no credit card required, compared to SMTP2GO's free plan, which allows up to 1,000 emails/month (200/day cap).
Can I use Elastic Email as a drop-in replacement for SMTP2GO?
Yes. Elastic Email supports both SMTP relay and a REST/HTTP API, so most integrations built for SMTP2GO can be repointed to Elastic Email's SMTP credentials or API endpoint with configuration changes rather than a rebuild. Both support standard authentication (SPF, DKIM, TLS/SSL).
Does Elastic Email support high sending volumes?
Yes. Elastic Email's Email API plans scale from 50,000 emails/month up to 10,000,000 emails/month via its pricing slider, with custom pricing available beyond that for high-volume senders.
Which is better for agencies or resellers - Elastic Email or SMTP2GO?
Elastic Email is the stronger fit for agencies that want to resell email sending under their own brand. Its Pro plan includes white-label SMTP and API, a UI hosted on your own domain, and CNAME setup. SMTP2GO offers subaccounts for managing clients but doesn't publish equivalent white-label branding features.
Does Elastic Email include email design tools, or is it just an API?
Elastic Email's Email API plans include a drag-and-drop Email Designer, a template gallery, and an AI Template Designer for generating layouts and copy from prompts. SMTP2GO does not include design or content-generation tools, as it's built purely as an SMTP/API relay
