SMTP2GO Pricing Plans and Cost Per Email at Every Monthly Volume

SMTP2GO costs $15 a month for 10,000 emails on Starter and $75 a month for 100,000 emails on Professional, which adds a dedicated IP address. Paying yearly costs ten months instead of twelve, so $150 and $750. A free plan covers 1,000 emails a month with a cap of 200 a day.

Those are the two prices on the plan cards. The slider above them moves through eight volume steps, and each step has its own price that only appears when you drag to it. The full ladder, read from the plan data the pricing page itself loads, looks like this.

Two notes on reading it. The slider labels its third stop 40K, while the plan data behind that stop is keyed to 50,000 emails at $30, so confirm the allowance at checkout if you are buying that step. And the page presents everything above 3 million as a custom Premier quote, even though its plan data carries list prices for 3 and 5 million. Treat those two rows as a starting point for a sales conversation.

SMTP2GO's Starter plan is $15 a month, and the $10 figure several pricing roundups quote appears to come from placeholder text in the page's markup. The raw HTML of the pricing page ships with a Starter card reading $10 a month, $100 a year and $1 per thousand extra emails. When the page loads in a browser, its script replaces that card with the live plan data, and the card you actually see says $15 a month, $150 a year and $1.20 per thousand.

The page title says the same thing in plain words, plans from $15 a month. A tool that reads the page without running its script picks up the placeholder instead, which is how $10 ends up in comparison tables. If you are budgeting from a third-party list, check it against the rendered page. The $5 difference is small, but a roundup that got this number wrong has probably not checked the overage rates either.

SMTP2GO costs $1.50 per 1,000 emails on the 10,000 plan and falls to $0.52 per 1,000 at one million a month. The unit price does not fall in a straight line. It rises from $0.60 to $0.75 between the 50,000 and 100,000 steps, because that is where the dedicated IP joins the plan. The division below is ours.

The practical reading is that 50,000 a month is the best value point on a shared IP, and that you pay roughly $45 a month for the step up to a dedicated address. SMTP2GO's own FAQ says a shared IP is the better choice below 100,000 emails a month, because a low or uneven volume gives mailbox providers too little to judge a dedicated address by. So the bump is not a penalty. You are buying something you only want once the volume is there.

SMTP2GO charges $1.20 per 1,000 extra emails on the 10,000 plan, $1.00 on the 50,000 step and $0.85 on Professional at 100,000, falling to $0.50 at one million. You can send up to three times your monthly allowance before sending stops, and the free plan allows no extra emails at all.

The third column is our arithmetic. It is the monthly volume at which the plan fee plus overage equals the price of the next step up. Below it, staying put and paying overage is cheaper. Above it, upgrade.

One detail is unusual. On the 10,000 plan the overage rate ($1.20 per 1,000) is lower than the plan's own unit price ($1.50 per 1,000). A sender who needs 20,000 emails pays $27 on the 10,000 plan with overage and $30 on the 50,000 step. Most relays price overage as a penalty. SMTP2GO, at the bottom of its ladder, does not.

An email addressed to several recipients counts once per recipient. A message to one address with two on copy uses three emails from the allowance.

SMTP2GO has a free plan with 1,000 emails a month, limited to 200 emails a day and to 25 an hour until you verify your sending domain. It includes 5 days of reporting and ticket support, with phone and chat for the first two weeks. It has no time limit and needs no credit card.

Signing up takes a work address at a domain you control, since public addresses such as Gmail and Yahoo are refused, and a phone number that can receive a verification code by text. The free plan cannot buy extra emails, so 1,000 is a hard ceiling. It is enough to wire up a contact form or test an integration. It is not enough to run a product on.

Paid plans come with a 30 day refund promise stated on the pricing page and repeated in the terms. The same terms reserve the right to change fees without advance warning, which matters if you are signing a yearly plan to lock a price.

At 10,000 emails a month SMTP2GO, Postmark and Mailgun all charge $15, and SendGrid's smallest paid plan is $19.95. At 100,000 a month SMTP2GO is $75 with a dedicated IP included, against $90 for Mailgun Scale and $89.95 for SendGrid Pro with theirs. SendGrid and Resend are cheaper at 100,000 if a shared IP is fine.

Competitor figures come from each vendor's own pricing page, as worked through on our SendGrid pricing, Mailgun pricing, Postmark pricing, Resend pricing and Amazon SES pricing pages. Where a provider has no plan at exactly that volume, the table uses the smallest plan that covers it.

So SMTP2GO is not the cheapest relay at any volume, because nothing beats Amazon SES on unit price. Its case is different. It is the cheapest of the managed relays that bundles a dedicated IP at 100,000, it answers the phone on every paid plan, and its bottom tier forgives a busy month better than the others do.

No. SMTP2GO's terms forbid unsolicited email of any kind and require every mailing list to be 100% opt-in. The terms name purchased lists, addresses collected from the internet and marketing leads, including lists built through LinkedIn or obtained from a third party, as lists you may not send to.

That rules out cold outreach as a use, however carefully it is done. The terms also ask that list members have been mailed within the previous three months and say bounce rates are monitored, so a cold list that slips through tends to surface quickly. An account closed for cause is the expensive outcome here, more than any line on the price ladder.

This is normal for a relay. SendGrid, Postmark, Mailgun and Amazon SES all take the same position, and we cover the detail in whether you can use SendGrid for cold email. Relays share IP reputation across customers, so they protect it.

Cold outreach belongs on mailboxes you own. A Google Workspace or Microsoft 365 inbox on a domain you control sends over its own SMTP at a human volume, and your reputation is yours alone. That is the setup ColdMailer is built around: you connect the inbox, import a list, and it writes one message per prospect, runs the follow-ups and caps each inbox's daily sends. Our guide to the best SMTP server for cold email compares the mailbox options, and the SMTP email sender page shows how the connection works.
