Buy e-mail packs
Add e-mails on top of your plan with one-time packs of 100 000: which plans can buy them, how they are used, how long they last and what happens when a campaign does not fit.
E-mail packs let you send more than your plan includes in a billing period, without changing the plan. One pack is 100 000 e-mails. When you finish these steps, the packs are on your balance and the invoice is in your purchase history.
Plan
E-mail packs are available on an active Growth, Pro or Scale plan, and only the workspace Owner can buy them. Starter does not include them. It does not matter whether you pay for your plan by card or by invoice: the packs themselves are always paid on Stripe's page.
Buy packs
Open E-mail sending
Go to Settings → Usage (/settings/usage) and find the E-mail sending section. The
E-mails this period meter shows how many e-mails you have left, counting your plan and your
packs.
Click Buy e-mails
The Buy e-mails button is under the meter. When you have used 80% or more of your e-mails, it moves into the warning under the meter. The Buy e-mails window opens with the size of one pack and its net price on your plan.
Choose the number of packs
In Number of packs enter how many you want, up to 10 at a time. The line below shows the total number of e-mails and the net price, and it updates as you type. Nothing has been charged yet. Cancel closes the window.
Pay on Stripe
Click Go to payment. Stripe's secure page opens with the amount to pay, including tax where it applies. This is a one-time payment, not a subscription.
Check your balance
After the payment you return to Settings → Usage and see Thank you for your purchase. The packs show up on the meter in a moment, and the purchase appears in Packs bought.
What a pack costs
The price depends on your plan, so this article gives no amounts. You see the net price in the Buy e-mails window and the amount with tax on Stripe's page before you pay. The price comes from the plan you are on at the moment of purchase. If you change your plan later, packs you already bought keep their e-mails and their price.
The invoice is issued automatically. Open it with View in the Invoice column of Packs bought.
How packs are used and how long they last
- Order: e-mails go out from your plan first. Packs are used only after the plan's e-mails run out, starting with the oldest pack.
- What uses them: everything that counts toward your plan's e-mails. The email overview lists what counts.
- Validity: each pack is valid for 12 months from the purchase. It does not reset when your plan renews. E-mails not sent within those 12 months expire.
Read the meter and the history
Under E-mails this period you see a line such as "Sent [N]. Plan: [N] per period, packs: [N]. The plan renews on [date]." With packs on your balance it adds "The next pack expires on [date]."
Packs bought has one row per purchase:
| Column | What it shows |
|---|---|
| Date | The day of the purchase |
| E-mails | The number of packs, their e-mails and how many remain |
| Amount | What you paid, and the net price per pack on that plan |
| Status | Active, Expired or Refunded |
| Valid until | The last day of the pack |
| Invoice | View opens the invoice |
Who cannot buy, and why
| Your situation | What you see |
|---|---|
| Starter | "E-mail packs are available from the Growth plan." and a See plans button. See Change your Zanfia plan. |
| Free trial | No Buy e-mails button, because packs top up an active paid plan. A trial with no plan chosen also shows the same message and button as Starter. |
| An older plan | Packs are available if your plan includes email campaigns, at the price shown in the window. Otherwise you see the same message as on Starter. |
| A plan paid in USD | "E-mail packs are not sold in your plan's currency yet. Contact us and we will set it up for you." |
| An Admin, Editor or Viewer | The meter and the history, but no Buy e-mails button. Ask the Owner to buy. |
| A Content Creator | No Usage tab. Ask the Owner to buy. |
If the window says packs aren't available on your plan, write to us.
Limits on buying
You can buy up to 10 packs (1 000 000 e-mails) in one billing period. To send more, contact us and we will set it up for you.
| Situation | What happens |
|---|---|
| You bought 10 packs this period | Buy e-mails is no longer offered. Once the meter reaches 80%, the warning says "You have bought the maximum number of packs for this billing period." You can buy again in the next billing period. |
| A payment is still open | Packs in an unpaid Stripe payment count toward the limit for up to 35 minutes, even if you left the Stripe page. You see "You have an open payment for [N] packs. Finish it in the Stripe tab, or try again at [time]." |
| Our sending capacity is booked | "We can't take this many extra e-mails right now: our sending capacity for this period is booked." The message says when to try again, or asks you to contact us. Nothing is charged. |
When a campaign does not fit
If a campaign is larger than what is left on your plan and packs, it is not sent or scheduled. You see This campaign does not fit your e-mails, with how many e-mails it would send, how many you have left from your plan and from packs, and how many are missing.
Click Buy e-mails in the dialog
You land on Settings → Usage with the Buy e-mails window open. It says "This campaign is [N] e-mails short." and the number of packs is already filled in.
Compare with a bigger plan
When a bigger plan would cost less than the packs for this campaign, the window also shows Cheaper: switch to [plan] with a See the plan button.
Pay and send the campaign
Pay as described above, then open the campaign again and send it.
If the dialog has no Buy e-mails button, it tells you what else you can do: choose a smaller audience, wait for the date your plan renews, change your plan, or ask the account owner to buy more e-mails.
Buy through the agent, the API or MCP
The agent, the Workspace API and MCP show the same balance and follow the same limits as the Buy e-mails window. None of them charges you: each one prepares a payment link, and you pay on Stripe's page. In the chat, the agent shows the link only after you approve its card; see Approve the agent's actions.
