A capable relay with a useful free tier, but check the volume caps and compare pay-as-you-go pricing before switching.

The bottom line

A solid email relay for modest volumes, though $10/month is worth comparing against usage-based options.

SMTP2GO covers transactional, general, and marketing sends, with automatic SPF and DKIM, delivery reports, account alerts, and spam-filter testing. The pricing page lists a free tier for up to 1,000 emails monthly; Starter is $10/month for 10,000 emails, while Professional is $75/month for 100,000 and adds a dedicated IP and email testing tools.

Reddit feedback is mostly positive but anecdotal: users in one thread report years of use without problems, while another thread questioned how often SMTP2GO gets recommended. Price-check carefully at low volumes: one Reddit commenter estimated AWS SES at $0.062 for 500 messages and 100 MB of attachment data, though that is not a like-for-like comparison.

Good fit if

  • Apps needing transactional email delivery
  • Small senders wanting a free tier
  • Teams needing reports and support channels

Skip it if

  • Senders needing more than 1,000 free emails
  • High-volume senders without a custom quote
  • Lowest-cost, very-low-volume email sending

01What SMTP2GO actually does

SMTP2GO is an outgoing email delivery service for apps, Outlook and marketing messages. It handles the sending side: transactional email from applications, general email from Outlook, and marketing email with an unsubscribe link. It is not just an SMTP relay; its feature set also includes delivery monitoring, email reports, spam-filter testing, and automatic SPF and DKIM handling for your domains.

The service says its multi-data-center infrastructure is designed to keep email sending during major internet outages. Reports cover sent messages, spam complaints, bounces and unsubscribe requests, while account alerts can flag potential problems such as a sudden rise in bounces. Spam-filter tests show how messages may appear in major email software and filters.

There is a free plan for up to 1,000 emails per month. Paid plans scale from 10,000 emails monthly on Starter to 100,000 on Professional; Premier is aimed at senders above 3 million monthly emails.

02Where SMTP2GO is strong

SMTP2GO puts useful delivery checks and sending tools in one service. Automatic SPF and DKIM handling can simplify domain setup, while reports bring sent email, bounces, spam complaints and unsubscribes into view. Alerts for issues such as a sudden bounce-rate increase are practical for teams that need to spot trouble without watching every send. The company also describes its multi-data-center infrastructure as a way to keep sending during major internet outages.

Plan choice is reasonably clear by volume and tooling:

  • Free: up to 1,000 emails monthly, automatic DKIM/SPF and real-time analytics.
  • Starter: 10,000 emails per month, 30 days of reporting, support by ticket, chat and phone, subaccount management and SMS messaging. It costs $10 month to month or $100 annually ($8.33 per month equivalent).
  • Professional: 100,000 emails per month, a dedicated IP, email testing tools, 30 days of reporting and SMS messaging. It costs $75 monthly or $750 annually ($62.50 per month equivalent).

Reddit feedback is mostly positive in the Reddit threads we read: several users report using the service without problems, though those comments are individual experiences, not delivery guarantees.

03Where it falls short

The free allowance is capped at 1,000 emails per month, so it is for low-volume sending, not a growing campaign. Starter stops at 10,000 emails monthly and Professional at 100,000; extra messages cost $1 per 1,000 on Starter and $0.85 per 1,000 on Professional. The pricing details put Premier above 3 million emails monthly but do not publish its price or the cost of its extra emails, making larger-volume budgeting harder.

Tool access also depends on the plan. The pricing page lists a dedicated IP and email testing tools for Professional and Premier, not Starter. Paid plans include 30 days of email reporting; the free plan's support features are limited to 14 days. A separate free-trial term is not listed in the pricing details.

At $10 a month, Starter is simple to price, but modest senders should compare it with usage-based services before committing. Reddit feedback is not uniformly reassuring: one commenter said SMTP2GO's signup verification email landed in junk. That is an anecdote, not proof of a delivery problem, but it is a reminder that no relay can promise inbox placement.

04SMTP2GO pricing: what you'll actually pay

SMTP2GO has a free plan for up to 1,000 emails a month. Its free-plan support features are limited to 14 days, so treat it as a low-volume starting point, not a full substitute for a paid support plan.

Starter costs $10 monthly for 10,000 emails. Professional jumps to $75 monthly for 100,000 emails, adding a dedicated IP and email testing tools. That is a $65 monthly increase; extra messages cost $1 per 1,000 on Starter and $0.85 per 1,000 on Professional. Premier covers more than 3 million emails a month, but its price is not published, so high-volume costs require a quote.

The pricing page lists annual billing at $100 for Starter and $750 for Professional—equivalent to $8.33 and $62.50 a month—with two months free. Those are annual commitments, not monthly payments at the lower rate. Reporting is limited to 30 days on the listed paid plans.

05Switching to (or from) SMTP2GO

Treat a move to SMTP2GO as a change to your sending setup, not a mailbox migration: the service handles outgoing email for apps, Outlook, and marketing messages. Before switching, inventory each sender and message type, then plan to update its sending configuration and verify delivery. SMTP2GO says it handles SPF and DKIM automatically for your domains, but confirm how that applies to your existing DNS setup before changing records.

The published pricing details list 30 days of email reporting on paid plans; they do not say whether reports or other account data can be exported, or whether data remains available after cancellation. Ask SMTP2GO before relying on it for long-term reporting. Lock-in terms are also not published on the vendor's site.

We don’t have Reddit posts or comments in the published material, so we can’t substantiate specific reasons users leave. Compare your required volume, reporting retention, and any quoted Premier price before switching; those are the clearest unresolved costs and constraints here.

From the threadsWhat users say

The Reddit comments are mostly positive anecdotes: users say SMTP2GO has worked for them over several years and describe it as inexpensive. The main reservations are one report of its signup email landing in junk and skepticism about how aggressively it is recommended on Reddit.

Questions people ask

Why use SMTP2GO?

SMTP2GO is an outgoing email delivery service for app-based transactional mail, general email from Outlook, and marketing messages. The published product facts list delivery monitoring, email reports, spam-filter testing, automatic SPF and DKIM handling, and account alerts. Reddit users describe it as inexpensive and dependable, though those comments are anecdotes, not a delivery guarantee.

What are common complaints about SMTP2GO?

The Reddit threads we read do not show a consistent pattern of service complaints. One user said SMTP2GO’s signup verification email went to junk, and another questioned how heavily it is recommended on Reddit. Other commenters said it worked well or that they had used it for years. These are individual reports, not a measure of overall performance.

Is SMTP2GO safe to use for email?

The published product facts list automatic SPF and DKIM handling, delivery monitoring, and account alerts, but they do not specify SMTP connection encryption or provide a security certification. Those features alone do not establish that a particular setup is secure. If security controls are a buying requirement, confirm the current technical details with SMTP2GO before switching.

Is SMTP2GO trustworthy?

The comments include users who report years of use and say the service worked well, but Reddit anecdotes are not an independent security or reliability audit. The published product facts describe delivery and monitoring features, not third-party certifications or uptime guarantees. We would treat user reports as useful context, then verify any required compliance and service commitments directly.

How much does SMTP2GO cost?

The listed Free plan allows up to 1,000 emails per month. Starter is $10 monthly or $8.33 per month with annual billing and includes 10,000 emails. Professional is $75 monthly or $62.50 annually for 100,000 emails. Extra emails cost $1 per 1,000 on Starter and $0.85 per 1,000 on Professional; Premier pricing is not published.
