How Much Does SMTP2GO Cost?
The real price of the transactional email relay, plan by plan, overages included.
Short answer: SMTP2GO has a permanent free plan (1,000 emails a month, no credit card), then paid plans from $10/month for 10,000 emails and $75/month for 100,000 emails, with a dedicated IP included. It is a transactional SMTP relay: you pay by the volume of emails sent, not by contact count or per seat. No lead database, no campaign builder, just sending that lands in the inbox. We walk through every plan, the overage charges, and what you really pay for your profile.

SMTP2GO, the key numbers
What each SMTP2GO plan costs
Here are the four plans, from free to custom. The price tracks the volume of emails sent per month, not your contact count. Cross a tier and you either move up a plan or pay for the overage per unit. A dedicated IP only arrives from the Professional plan up. Prices checked June 2026 on the official page.

Prices checked June 2026 on smtp2go.com/pricing and cross-referenced across several sources. The Starter plan sometimes appears at $15 to $19/month on third-party listings, but the official page shows $10/month in June 2026. Billing is by volume sent: neither seats nor stored contacts raise the bill, only the number of emails.
SMTP2GO, where the extra cost hides
The headline price covers sending up to a tier. Beyond it, a few mechanisms can raise the total. Here is what to watch before you pick a plan.
The volume tier
The price tracks tiers: 10,000 (Starter), 100,000 (Professional), 3M+ (Premier). If your volume regularly crosses a tier, move up a plan, it costs less than paying overages over and over.
Overage charges
Past your monthly quota you pay $1 per 1,000 emails on Starter and $0.85 on Professional. A one-off spike stays painless, but a steady overage quickly costs more than upgrading.
The dedicated IP
It is included from the Professional plan ($75/month), not on Starter. If you want a dedicated IP for sender reputation at a lower volume, that is a reason to move up a plan sooner.
What SMTP2GO does not do
It is not a full ESP: no contact database, no marketing automation, no A/B testing, and log retention caps at 30 days. If you need marketing campaigns, plan for a second tool, and a second budget.
- Sending under 1,000 emails/month? The free plan is enough.
- Crossing your tier often? Upgrade rather than pay overages.
- Want a dedicated IP? It arrives on the Professional plan.
- Need marketing automation? SMTP2GO does not do it, add another tool.
- Want long history? Logs are kept 30 days, export if you need more.
How we size the real cost
SMTP2GO's price depends on a single variable: the number of emails sent per month. No stored contact is billed, no seat. To size the real cost, take your monthly volume, pick the tier just above it, and add the overage if you spill over. Here are the benchmarks.

- Tier chosenFree, 10K, 100K or 3M+Plan

- 100,000 emails: $89.95/month (Pro)
- Dedicated IP included on the Pro plan
Entry prices checked June 2026 on the official pages. SMTP2GO is the only one of the three to keep a generous permanent free plan (1,000/month) and to include the dedicated IP at $75/month for 100,000 emails, where Postmark climbs past $133 and SendGrid asks $89.95. Postmark and SendGrid keep strong deliverability reputations, but bill more at volume.
So, is SMTP2GO expensive?
Our take after testing it: for pure transactional sending, the value is excellent. Here is when it pays off, and how to pay less.
Good value if…
You want a reliable SMTP relay for an app, a SaaS or a fleet of devices. The free plan covers a start, and at $75/month for 100,000 emails with a dedicated IP included, SMTP2GO undercuts Postmark and SendGrid at the same volume while keeping excellent deliverability.
Less of a fit if…
You want a full marketing platform. SMTP2GO handles no contact database, no campaigns, no automation: you would need a second tool. For email marketing in a single product, a tool like Brevo is a better fit.
How to pay less
Start on the free plan to validate deliverability, pay annually to save around two months, and pick the tier just above your real volume to avoid overages. Only move up to Professional if you genuinely need the dedicated IP.
- Start on the free plan: 1,000 emails/month, no card.
- Pay annually: about two months free.
- Pick the tier as close as possible to your real volume.
- Watch your overages so you do not pay them on repeat.
- Take the dedicated IP (Professional) only if reputation demands it.
Frequently asked questions about SMTP2GO pricing
How much does SMTP2GO cost per month?
SMTP2GO has a permanent free plan that covers 1,000 emails a month, with no credit card. Paid plans start at $10/month for 10,000 emails (Starter), then $75/month for 100,000 emails (Professional), with a dedicated IP included at that tier. Above that, the Premier plan is custom-priced for 3 million emails and up. Billing is by the volume of emails sent, not by contact count or per seat. The smart move is to start on the free plan, then pick the tier just above your real volume.Does SMTP2GO have a free plan?
Yes, and it is permanent, not just a trial. SMTP2GO's free plan lets you send 1,000 emails a month, with no credit card, with a cap of 200 emails per day. It includes the SMTP relay and the HTTP API, log retention for 5 days, and phone and chat support during the first 14 days. It is enough to test the integration of a small app or a side-project. For higher volume or longer log history, you need to move to a paid plan.How much does SMTP2GO cost for 100,000 emails a month?
For 100,000 emails a month, the Professional plan runs $75/month, with the dedicated IP included and the email testing tools. That is one of the best ratios on the market at this volume: Postmark climbs between $133 and $177/month depending on the plan, and SendGrid asks $89.95/month on its Pro plan for 100,000 emails. If you regularly exceed 100,000 emails, the overage is $0.85 per 1,000 on Professional, or it is better to move to the custom-priced Premier plan.How do overages work on SMTP2GO?
Past your plan's monthly quota, SMTP2GO charges an overage. On the Starter plan it is $1 per 1,000 extra emails; on Professional it is $0.85 per 1,000. So a one-off volume spike stays painless. But if you exceed your tier every month, it works out cheaper to move up a plan rather than pay the overage on repeat. Watch your volumes in the dashboard to anticipate, and switch tiers before the overages pile up.Is the dedicated IP included in SMTP2GO's price?
Yes, but only from the Professional plan, at $75/month. On the free plan and the Starter plan there is no dedicated IP: you send from SMTP2GO's shared IPs, which remains very solid for deliverability thanks to their high-reputation infrastructure. If you need a dedicated IP to control your sender reputation at a lower volume, that is a reason to move up to Professional sooner. On SendGrid the dedicated IP also arrives on the Pro plan, and on Postmark it is an add-on.Is SMTP2GO cheaper than SendGrid or Postmark?
At equal volume, yes in most cases. For 100,000 emails a month, SMTP2GO costs $75/month with the dedicated IP included, against $89.95/month for SendGrid (Pro plan) and between $133 and $177/month for Postmark. SMTP2GO is also the only one of the three to keep a generous permanent free plan: 1,000 emails a month, where Postmark caps at 100 and SendGrid retired its permanent free plan in 2025. Postmark and SendGrid keep an excellent deliverability reputation, but bill more at volume.Is there a discount for paying SMTP2GO annually?
Yes. The official page advertises about two months free for paying annually, roughly a 16% saving versus monthly billing. Confirm it at checkout, since the annual price display has at times been confusing. That is the main lever to pay SMTP2GO less, alongside picking a tier matched to your real volume. There is no reliable recurring official promo code, so be wary of third-party coupon pages that claim otherwise.Does SMTP2GO bill per contact or per volume?
By the volume of emails sent per month, never by the number of stored contacts or per seat. That is an important difference from email marketing platforms like Mailchimp or ActiveCampaign, which bill by list size. With SMTP2GO you can hold a large address base without paying more as long as you do not send more emails. The price only moves with the number of emails relayed, which makes the cost very predictable for transactional or bulk sending.How long does SMTP2GO keep email history?
Log retention is 30 days on the paid Starter and Professional plans, and 5 days on the free plan. You get detailed tracking of sends, opens and clicks over that window, but no long-term history by default. If you need to keep your data beyond 30 days, plan to export it regularly or wire your own tools through the API. It is one of the few limits of the product, worth keeping in mind if compliance requires longer archiving.Can I cancel or change SMTP2GO plans easily?
Yes, the subscription is managed from your account and you can change tier up or down as your volume shifts. There is no long commitment on the monthly plans. If you paid annually, check the prorated refund terms before moving down a plan. Also remember to export your logs before closing your account, since retention caps at 30 days. For very high volume, the Premier plan is negotiated directly with the sales team.
