Email Submit Offers vs Zip Submit Offers: Which Convert Better?
Email submit vs zip submit CPL offers compared: conversion rates, payouts, GEO restrictions, scrub rates, and EPC math. Which single-field offer should beginners promote?
Email submits and zip submits are the two simplest offer types in CPL — one field, one click, one conversion. They are where most beginners earn their first dollar, and they sit at the top of nearly every offer type breakdown for a reason.
But they are not interchangeable, and the difference matters more than most guides admit.
The short answer: Zip submits convert slightly better per click (typically 1–3 percentage points higher) because typing a zip code feels like giving away nothing. But they only work on US traffic. Email submits work worldwide but face heavier scrub rates. For pure US traffic, test zip first; for anything international, email is your only option of the two.
Here is the full comparison so you can pick the right one for your traffic.
What Is an Email Submit Offer?
An email submit offer pays you when a user enters their email address into a single-field form and hits submit. That is the entire conversion — no email confirmation, no second page, no purchase. The advertiser gets a lead for their marketing funnel; the user usually gets entered into a sweepstakes or promised a free sample/gift card.
- Typical payout: $0.50–$1.50
- Typical flow: Landing page → email field → submit → conversion fires
- GEO availability: Global — US, UK, CA, AU, and most of Europe and LATAM all have email submit inventory
These offers are the entry point of the free gift and sweepstakes ecosystem — most of the funnels described in our free gift CPL offers guide start with an email or zip submit as the first conversion step.
What Is a Zip Submit Offer?
A zip submit offer pays you when a user enters their ZIP/postal code into a single-field form. Same one-field mechanic, different data point. The advertiser uses the zip for geo-targeted marketing (local offers, regional campaigns, retail partnerships), and the form usually feeds into the same sweepstakes-style funnels.
- Typical payout: $0.80–$2.00 (slightly higher than email submits)
- Typical flow: Landing page → zip field → submit → conversion fires
- GEO availability: US-only, almost without exception. A zip code field is meaningless to non-US users, and advertisers only pay for US zips
Head-to-Head Comparison
| Dimension | Email Submit | Zip Submit |
|---|---|---|
| What user enters | Email address | ZIP/postal code |
| Typical payout | $0.50–$1.50 | $0.80–$2.00 |
| Beginner conversion rate* | 3–8% cold, 8–15% warm/incentivized | 5–10% cold, 10–18% warm/incentivized |
| GEO coverage | Global | US only |
| Perceived privacy cost | Higher (“they’ll spam me”) | Lower (“it’s just a zip”) |
| Scrub rate risk | Higher | Moderate |
| Advertiser lead quality demand | Email validity, engagement | Zip validity, US residency |
| Mobile friendliness | Good | Slightly better (numeric keypad) |
| Availability on networks | Every CPL network | Every CPL network, US section |
*Conversion rate = clicks → leads, assuming compliant traffic matched to the offer’s audience. Your numbers will vary; these are planning ranges, not promises.
Why Zip Submits Usually Convert Better
The entire difference is psychological friction. An email address feels personal — users hesitate because they expect spam. A zip code feels anonymous. Nobody mentally associates “90210” with their inbox getting flooded.
That hesitation gap shows up in the data: on the same traffic source with the same pre-lander, zip submits typically convert 1–3 percentage points higher than comparable email submits. On a 2,000-click test, that is 20–60 extra leads from identical traffic.
Two secondary factors help too: numeric keypads on mobile make zips faster to type than an email address, and typo rates are lower (5 digits vs. a full email string — fat-fingered emails cause validation scrubs later).
The GEO Constraint Changes Everything
The zip submit advantage is real but locked to US traffic. If your visitors are 60% non-US — common for SEO content sites — most of them physically cannot convert on a zip submit. Showing a US-only offer to international traffic wastes the click entirely unless you geo-redirect.
This is where beginners burn money: they see “zip submits convert better,” run global traffic at them, and wonder why overall conversion is terrible. The fix:
- US-dominant traffic (paid US campaigns, US Pinterest, US-focused content) → zip submits are the better default test
- Mixed/international traffic (most organic SEO, global social) → email submits, or split by geo if your tracker supports redirects
- Check your actual geo split in GA before choosing — do not assume

Scrub Rates: The Hidden Difference
“Scrubbing” is when the network/advertiser invalidates some of your leads after the fact — you see 50 conversions and get paid for 42. Both offer types get scrubbed, but for different reasons:
Email submits face harsher scrubbing because the email itself is the product. Advertisers run validation: disposable domains (mailinator etc.), role addresses (info@), malformed entries, duplicates, and known low-engagement patterns all get rejected. Incentivized traffic makes this worse — users motivated by a reward enter junk emails. Expect 10–20% scrub on incentivized email submits, 5–10% on cleaner traffic.
Zip submits scrub mainly on geo-mismatch (VPN users, non-US IPs entering zips) and duplicates. The zip itself is almost impossible to “invalid” — 90210 is always real. Expect 5–12% scrub, mostly geo-related.
Either way: track your approval rate (paid leads ÷ tracked leads) per offer, not just raw conversions. Our guide on avoiding low-quality leads shows how to spot scrub patterns in your data.
The EPC Math (Same Traffic, Both Offers)
Run the numbers with realistic mid-ranges — 1,000 clicks of US traffic through a simple pre-lander:
| Email Submit | Zip Submit | |
|---|---|---|
| Clicks | 1,000 | 1,000 |
| Conversion rate | 6% | 8% |
| Tracked leads | 60 | 80 |
| Approval rate | 88% | 90% |
| Paid leads | 53 | 72 |
| Payout | $1.00 | $1.25 |
| Revenue | $53 | $90 |
| EPC | $0.053 | $0.090 |
The zip submit wins by ~70% on identical US traffic — higher conversion, higher payout, slightly better approval rate. This is why the payout vs conversion math matters more than the payout sticker: a $0.25 payout gap compounded with a 2-point conversion gap is a massive EPC difference.
Now the same 1,000 clicks with 50% international traffic: the zip submit loses every non-US click (say 450 of 500 international clicks bounce), and its effective EPC collapses below the email submit’s. GEO beats offer type as the deciding factor.
Which Should YOU Promote?
Choose zip submits if: your traffic is 70%+ US, you want the highest EPC per click, and your network shows strong zip inventory in your niche. This is the default best first test for US paid traffic or US-focused content.
Choose email submits if: your traffic is international or mixed, you promote in geos where zip-format offers do not exist, or the specific email-submit funnel (free gift, sweepstakes) matches your content better. Also the right choice when the email submit’s landing page and angle simply look stronger than the zip alternatives in your network.
Choose both if: you can geo-redirect (BeMob free tier does this) — US clicks to zip submits, international clicks to email submits. This is the setup that maximizes total EPC on mixed traffic, and it is exactly the kind of test to run with the simple weekly testing routine.
Whichever you pick, run it through the full evaluation first — terms, caps, allowed traffic — using how to evaluate a CPL offer, and read the offer’s fine print with how to read CPL offer terms. Single-field offers have some of the strictest traffic rules in CPL precisely because they convert so easily.
Where to Find These Offers
Every major beginner-friendly network carries both types in volume. Payouts on the identical advertiser offer often differ $0.10–0.30 between networks, so compare before committing traffic:
- CPAGrip — deepest incentivized email/zip inventory, content-locker friendly
- CPAlead — strong sweepstakes email submits, good mobile coverage
- AdWork Media — solid US zip submit selection
- MyLead — best option for non-US email submits across EU geos

FAQs
Are email submit and zip submit offers legit?
The offers themselves are legitimate CPL lead-gen — advertisers pay for the data to fuel marketing campaigns. The sketchy part is usually the funnel around them: overpromising “free iPhone” claims, fake countdown timers, or impossible prize odds. Promote them honestly (“enter for a chance to win”) and they are compliant; wrap them in false claims and both the network and the FTC will have problems with you. See are free gift offers legit for the full breakdown.
Why did my email submit conversions disappear from my dashboard?
Almost always scrubbing: the advertiser’s validation rejected the emails (disposable domains, typos, duplicates, fake patterns) and the network reversed those leads. This is normal at 5–15%; above 25% means your traffic quality has a problem or the offer is aggressively shaved — test the same traffic on a different network’s version of the offer and compare approval rates.
Can I complete email/zip submit offers myself to test them?
Usually no — most offer terms explicitly prohibit self-completions and incentivized self-signups, and networks fingerprint this (same IP, device, payment details). Violating it is a fast route to a ban. Test the tracking with a test postback instead, and test the funnel by clicking through without submitting, as covered in our first offer walkthrough.
Do email submits work on mobile traffic?
Yes — single-field forms are inherently mobile-friendly, which is a big part of why these offers dominate incentivized mobile funnels. Zip submits have a slight edge on mobile (numeric keypad, 5 digits vs. a full email), but both convert well on phones. Always test the offer flow on a real phone before sending traffic.
What payout should I expect for a first email/zip submit campaign?
Plan around $0.50–$1.50 for email submits and $0.80–$2.00 for zip submits on beginner networks. Anything advertising $3+ for a single-field submit deserves scrutiny — either it has a hidden second conversion step (read the terms), brutal scrub rates, or traffic restrictions that make it unusable for you. Sort by network EPC, not payout, and let the EPC math decide.
