Yes. FIRST20 is still live on premiuminboxes.com, and it takes 20% off your first order.
It works on Google Workspace and Microsoft 365 inboxes, and on both the Standard tier at $3.50 per inbox and the Insured tier at $4.50 per inbox.
It is a first-order code. Your renewals bill at list price, which already steps down to $3.00 and $2.80 per inbox once you pass 250 and 1,250 inboxes.
I run every client’s cold email infrastructure on Premium Inboxes, and FIRST20 is the code I hand over whenever a new client sets up their first workspace. That is the whole reason I keep an eye on whether it still applies.
One thing to know before you rush off to checkout: because the code only fires once, the size of your first order decides how much you actually save. I will show you the numbers further down, and I will also show you the one order size where you should round up instead of down.
Last checked: 8 October 2026. If anything changes, I update this line first.
Why I Put Every Client on Premium Inboxes Before We Even Talk About Discounts
A quick word on the provider before the coupon, because a 20% discount on inboxes that die in three weeks is still a terrible deal.
I have rebuilt enough burned infrastructure for clients to have one rule now: official accounts only. Premium Inboxes sells real Google Workspace and Microsoft 365 business accounts, not farmed or cracked logins that get wiped in a batch.
The second reason is that I never touch the technical setup. They handle domains, DNS, SPF, DKIM, DMARC, inbox creation, profile photos, and they upload the accounts straight into Smartlead or Instantly with warmup switched on.
Most orders are live in under six hours. For a client who signed yesterday and wants to send next week, that timeline matters more than the price.
The third reason is the one that quietly saves the most money. If an inbox gets flagged, they replace it free, same day, with no cap on how many times. I used to budget 10% to 15% extra inboxes as a buffer. I do not anymore.
Support is a shared Slack channel with Richard, the founder, and his infra team. When something breaks at 11pm before a client launch, a human who knows DNS answers, not a ticket bot.
They sit at 4.9 out of 5 on Trustpilot across several hundred reviews, and a surprising number of those reviews mention Richard by name. That is unusual for an infrastructure vendor and it matches my experience.
So the coupon is a bonus. The reason I recommend the service would hold at full price, which is exactly why I am comfortable telling you to use the code.
What FIRST20 Actually Discounts (And What It Does Not)
The name says it. 20% off, first order. Here is how that plays out against the real plan list.
It works on both providers. Google Workspace and Microsoft 365 inboxes are priced the same at Premium Inboxes, and the code applies to either. If you split a client across both, which I recommend, apply it to whichever order you place first.
It works on Standard and Insured. Standard is $3.50 per inbox and Insured is $4.50 per inbox with the account manager, Slack channel and 24-hour monitoring. The code takes 20% off either one.
It is first order only. Once that first invoice is paid, the next cycle bills at list price. Billing runs every four weeks, so the discount covers one four-week cycle, not a calendar month.
It scales with the order. 20% of a 30-inbox order is small. 20% of a 240-inbox order is real money. Since it fires once, front-load the inboxes you know you will need.
It does not cover domains. Premium Inboxes expects you to bring your own domains and give them access to set DNS. You buy those at your registrar, so there is nothing on the invoice for the code to touch.
It does not touch the Email Control Centre tier. That is a $7,500 per month managed operations tier, by application only, and it is not something you check out with a coupon.
Annual billing is a separate question. The pricing page shows a 20% saving for annual billing. Try the code on an annual order and read the summary before you pay. If the two do not stack, the annual saving is usually worth more over a year than a one-time 20%.
How to Apply FIRST20 at Checkout, Step by Step
The whole thing takes about two minutes. The only place people get stuck is finding the coupon field, so I have called that out.
- Open the Premium Inboxes pricing page. Pick Google or Microsoft at the top, then Monthly or Annual.
- Click Get Started on the tier you want. You land on a Chargebee checkout page on the premiuminboxes.chargebee.com subdomain. That is their billing system, not a third-party reseller.
- Set your quantity. The pricing buttons default to 1 or 30 inboxes, so change it to the number you actually need before you do anything else.
- Look for the coupon link in the order summary. On Chargebee checkouts it is a small text link along the lines of “Add coupon” rather than a big box, which is why people miss it.
- Type FIRST20 in capitals, with no spaces, and click Apply.
- Read the order summary. You should see a 20% discount line and the total drop. If it has not dropped, stop and check the section below before you enter card details.
- Pay, then complete the onboarding form: your domains, DNS access, sequencer login, sender names and photos. That form is the last technical thing you touch.
One more route for agencies. Premium Inboxes has a client API, and the purchase endpoint accepts a coupon field. If you spin up client workspaces by code, you can pass FIRST20 in that field on a workspace’s first order instead of going through the checkout page.
The Math: What 20% Off Looks Like on a Real First Order
Here is what the code is worth at the order sizes I see most often. All figures are per four-week billing cycle, before tax, using the list prices on the pricing page as of October 2026.
| First order | Tier and price per inbox | List total | With FIRST20 | You save |
|---|---|---|---|---|
| 10 inboxes | Standard, $3.50 | $35.00 | $28.00 | $7.00 |
| 30 inboxes | Standard, $3.50 | $105.00 | $84.00 | $21.00 |
| 100 inboxes | Standard, $3.50 | $350.00 | $280.00 | $70.00 |
| 249 inboxes | Standard, $3.50 | $871.50 | $697.20 | $174.30 |
| 250 inboxes | Growth, $3.00 | $750.00 | $600.00 | $150.00 |
| 100 inboxes | Insured, $4.50 | $450.00 | $360.00 | $90.00 |
Two things jump out of that table, and both change how I tell clients to order.
Round up at the tier line. 249 inboxes on Start Up costs $871.50 at list. 250 inboxes drops you into Growth at $3.00 and costs $750.00. You get one more inbox and pay $121.50 less, before the coupon even applies.
Front-load the first order. A client who starts with 30 inboxes and adds 70 next month saves $21 with the code. The same client ordering 100 up front saves $70. Since replacements are free and you only pay for what you keep, there is little downside to ordering what you will need in month two.
For scale, 30 inboxes at 15 cold emails each is about 450 sends a day. 100 inboxes gets you to roughly 1,500 a day. Size the first order to the volume your campaign actually needs, then apply the code once.
Why FIRST20 Might Not Apply (And the Fix for Each)
When a client messages me saying the code failed, it is almost always one of these. Work down the list in order.
You typed it in lowercase or with a space. Coupon fields are usually case sensitive. Clear the field, type FIRST20 in capitals, apply again.
You cannot see the coupon field. On the Chargebee checkout it is a small link, not a box. Scroll the order summary panel, and if an ad blocker or privacy extension is running, open the checkout in a clean window.
This is not your first order. If your email is already attached to a Premium Inboxes account with a past order, the code will not fire. There is no trick around that. Use the volume tiers and annual billing instead, both covered below.
You already applied a different code. One coupon per checkout. Remove the other one first, then add FIRST20.
You are on the Email Control Centre application. That tier is quoted and onboarded by application, not a checkout page. Nothing to apply.
You are trying a code from a coupon aggregator. This is the big one. Search for Premium Inboxes coupons and you will find pages promising 30%, 32% and even 60% off, plus codes like INBOXFIRST or LEADACADEMY20.
I have never seen a 30% or 60% Premium Inboxes code apply at checkout, and none of those pages show you an order summary where it did. They exist to rank for the search term and farm clicks.
FIRST20 comes from Premium Inboxes’ own affiliate program, which is why it works. The company issues codes to Gold tier partners, and 20% is the discount level that program supports. Anything bigger is a red flag, not a better deal.
If you have run through all of that and the summary still has not changed, message the Premium Inboxes team from the contact page before you pay. They answer fast, and I would rather you get the discount than guess.
Other Ways to Pay Less on Premium Inboxes After the Code Is Used
FIRST20 is a one-time win. These are the levers that keep working every cycle, and together they matter more than the coupon.
Cross the volume lines. Pricing drops from $3.50 to $3.00 per inbox at 250, and to $2.80 at 1,250. If you manage several clients under one agency account, consolidating workspaces under that account can push you over a line sooner.
Switch to annual once you trust the setup. The pricing page offers 20% off for annual billing. I would not do this on day one. Run two or three cycles, confirm the inboxes behave in your sequencer, then lock in the annual rate.
Pick Standard unless you need the extras. Insured adds a dedicated account manager, a private Slack channel, priority builds and 24-hour monitoring for $1 more per inbox. For a 300-inbox agency that is $300 a cycle. Worth it for some, wasted for a 20-inbox founder.
Stop buying buffer inboxes. Replacements are unlimited and free, so the old habit of ordering 10% extra as insurance just costs you 10% extra. Order what you will send from.
Size it with their calculator. The site’s calculator uses 15 cold emails per inbox per day as the safe ceiling. Most over-spending I see is people running 30 or 40 per inbox and then paying for replacements they would not have needed.
Earn it back as a partner. If you recommend tools to other founders or agencies, the Premium Inboxes affiliate program pays 10% recurring at Bronze, 15% at Silver, and 20% lifetime at Gold. One referred client at 100 inboxes covers your own 30-inbox bill.
Is Premium Inboxes Worth It Without Any Discount?
For the teams I work with, yes, and I want to be specific about who that is so you can tell if it is you.
You are a founder or small sales team running 10 to 250 inboxes. This is the sweet spot. You get configured DNS, a six-hour turnaround, free replacements and a human in Slack, for less than most people pay buying Workspace seats direct and doing the setup themselves.
You are an agency onboarding clients every week. Separate workspaces per client, an API to automate orders, and a provider who does not disappear when something breaks. The time you do not spend on DNS is billable time.
You have been burned by cheap inboxes. If you have watched a campaign go dark because a batch of farmed accounts got wiped, the extra dollar per inbox for official accounts is not a cost. It is the thing that keeps your pipeline alive.
Where I would hesitate is different from where most reviews put it.
If you want to own every admin console yourself, a managed provider will always feel like one layer removed, even with full admin access. Some operators prefer that control and are willing to pay for it in hours.
If your whole operation is under 50 emails a day, three or four inboxes on your own domain will do, and a done-for-you provider is overkill until you scale.
If you are chasing the absolute lowest per-inbox number, there are cheaper resellers. I have used some. The savings tend to show up again as replacement costs and lost sending days.
My verdict is simple. Buy it for the official accounts and the replacement policy, use FIRST20 because it is sitting there, and judge the service on cycle two when the discount is gone. That is when you find out what a provider is really like, and this one holds up.
