ZeroBounce Credits Expired or Gone? What to Check and What to Do Next

If your ZeroBounce credits look expired or have gone missing, do not assume they are lost and do not assume they are safe. As of 10 November 2026, ZeroBounce's own pricing page says credits never expire while you have an active ZeroBounce One subscription, and that for non-subscribers "expiration rules may apply depending on when your account was created." So which rule applies to you depends on your account's history. Find out first, then decide whether a pack is the right way to buy at all. If you decide to move, SimpleVerifier Pro is $39 a month: the first 100,000 checks a month at full speed, then slower, never cut off, and you can run 100 free checks before you commit.

Everything below about ZeroBounce comes from its pricing page, read on 10 November 2026. Terms differ by account and change over time, so treat your own account and its terms as the authority.

What ZeroBounce's pricing page says about expiry

Three statements on the page matter here:

• Subscribers. Credits never expire while you have an active ZeroBounce One subscription, and unused credits roll over each month.
• Non-subscribers. Expiration rules may apply depending on when your account was created. The page also says expiry can depend on when credits were purchased, granted or received through a promotion, and sends you to the applicable terms or your account manager.
• Cancellation. The page says you can cancel a subscription anytime.

Notice what is not there: no single expiry period that applies to everyone. That is why a forum post saying "mine expired after a year" and another saying "mine never did" can both be true. We are not saying either of them is wrong. We are saying the answer sits in your account and its terms.

Step 1: find out what actually happened

Spend ten minutes on this before you spend any money.

1. Check the balance and the history. Look at the credits page in your account. Does it show an expiry date next to a batch, or a zero balance with no explanation?
2. Note the dates. When did you buy the credits? When was the account created? Were any credits a free grant or a promotion?
3. Check whether a subscription lapsed. If you had a subscription that ended, the "while you have an active subscription" wording on the page is worth asking about.
4. Read the terms in force on the purchase date. Terms are versioned. Ask support which version applies if it is not clear.
5. Write to support. Quote the dates and the balance, and ask three plain questions: what happened to these credits, which term applied, and whether anything can be restored. Keep the reply.

Do not expect a particular answer. Some accounts will have a clear reason, some will not, and a restore is the vendor's decision. Whatever it says, you now know where you stand.

Step 2: decide whether credits are the right way to buy

Credits suit a small number of lists a year. If you buy a pack, use half, and come back eight months later, you have just met the exact risk you are annoyed about. The credits vs monthly plan guide explains the sum, and the credits vs monthly plan calculator does it with your own numbers. It holds no vendor prices, so type in the real figures from ZeroBounce's pricing and ours.

A short rule of thumb:

• Verifying a few times a year, small lists. Credits can honestly cost less. A competitor may be cheaper than us at that volume and that is fine.
• Verifying every week or every month. A monthly plan removes the expiry question, because you pay for the month you use.
• Bursty volume. Price a quiet month and a busy month, not only the average.

Step 3: migrate without losing anything

Moving from ZeroBounce does not need a big-bang cutover. Run both for a week.

1. Export your history. Download each list you verified, keeping the result column. Those files are your suppression record and your proof of what was checked.
2. Export your suppression and do-not-mail lists from your sending tool, not only from the verifier.
3. Pick a test slice. Take 100 addresses you already have ZeroBounce results for, including some marked invalid, some catch-all and some valid.
4. Verify the slice with the 100 free checks on /verify. No card needed.
5. Compare. Put both result files into the compare email lists tool or compare two CSV files, keyed on the email address. Look at disagreements one by one rather than counting them. If a status differs, ask why: a catch-all domain, a mailbox that changed, a timeout.
6. Re-verify what is due. Anything older than a few months should be checked again, whichever tool does it. Addresses decay.
7. Switch your next real list. Upload it as CSV (up to 100,000 rows per file) and export valid, risky and invalid separately.
8. Only then cancel. If you have a subscription at ZeroBounce, cancel it once you have used what you paid for. If you still hold credits that have not expired, use them first.

What to watch for with the results

Result categories are not a standard. One tool's "risky" may be another's "unknown" or "accept-all". When you compare, map each tool's labels to what you will do with the address: send, test carefully, or drop. Our catch-all guide and catch-all checker help with the middle group. Do not read one tool as "right" because it is stricter or looser. Judge by bounces on a real send, from a small sample first.

How SimpleVerifier fits

Pro is $39 a month. The first 100,000 checks a month run at full speed, then they run slower, and you are never cut off. That is the "unlimited" claim and it is only that: unlimited email verification with that fair-use pace after 100,000. Pro runs real SMTP mailbox checks, detects catch-all, disposable and role addresses, takes CSV uploads up to 100,000 rows, and exports valid, risky and invalid separately. The API is included at 10,000 calls a month, then $1.50 per 1,000, and it is metered apart from bulk verification.

There is no pack to expire. The month ends, the next one starts, and if you stop needing it you cancel.

Mistakes to avoid when credits go missing

• Assuming the worst in your first message. Support reads many tickets. A short, dated, factual message gets a faster and clearer reply than a complaint.
• Re-buying to "get back to work" the same day. If you have a campaign waiting, verify the most urgent slice with the free checks while you wait for an answer. The 100 free checks are enough to clear a small send.
• Throwing away the evidence. Keep invoices, the credits page, screenshots of the balance and the support reply. If you later dispute a charge or ask for an exception, you will want them.
• Forgetting the other cost. Credits are one line of the bill. Time spent chasing a balance is another. If you notice that you are checking expiry dates every quarter, that alone tells you the pack model does not fit how you work.
• Moving everything at once. Lists you verified months ago should be re-verified anyway, so you lose nothing by letting the new tool do the next list while the old account winds down.

A calendar habit that avoids this next time

Whatever tool you use, write the expiry rule in your own notes the day you buy: the vendor, the date, the pack size and the rule as written on the page that day. Put a reminder a month before any date that could matter. With a monthly plan the reminder becomes your renewal date and nothing else, which is the main practical argument for that model.

Bottom line

Check the dates, ask ZeroBounce in writing what happened and keep the answer. Then choose how to buy: credits for rare small lists, a monthly plan for regular ones. Test the 100 free checks on a slice you already have results for, compare file against file, and move the next real list once the two agree on what matters to you.
