What Dragonfish Actually Does To Your Email List

Most "list cleaning" services run one check. Does the email bounce, yes or no. Done. That's not cleaning. That's a coin flip.

When Dragonfish scrubs your list, every single email gets put through 28 separate forensic checks before we decide if it stays, goes, or gets flagged. Think of it less like spellcheck and more like a background investigation on every subscriber you have.

Here's what we actually look at:

• Is this email even real? We ping the mail server directly and get a score back. Does the address exist? Is the server rejecting mail? Is it a catch-all that says "yes" to everything? We catch all of it.
• Is this person a complainer? We identify frequent "spam" clickers before you mail them, because one of them can poison deliverability for your entire list.
• Is it a spam trap or honeypot? Fake emails planted by ISPs and blacklist operators. Hit one and Gmail, Yahoo, and Outlook can throttle your whole domain overnight. We flag high, medium, and low trap probability.
• Is it disposable? Mailinator, TempMail, all the 10-minute inbox services fraudsters use. Gone.
• Is it a role address? admin@, info@, sales@, webmaster@. These almost never convert. We tag every one.
• Has it been in a data breach or shown recent fraud activity? Chargebacks, fake signups, compromised devices. If this email has misbehaved anywhere on our threat network recently, you'll know.
• What's the Fraud Score? Every email gets a 0 to 100 score based on reputation and recent behavior. Above 75 is suspicious.
• Is the domain itself sketchy? Risky TLDs, missing SPF/DMARC/MX records, brand-new domains. Red flags.
• Is this a real person or a bot-created account? We score actual human activity and give every domain a final risk classification: trusted, positive, neutral, suspicious, malicious, or not rated.
• Yahoo and Outlook specific tagging. The strictest filters in email, tagged separately so you can warm, throttle, or exclude them.
• Final deliverability verdict. After all 28 signals, every email gets a plain-English rating: high, medium, or low likelihood of landing in the inbox.

What this means for you: You stop mailing the ghosts, the spam traps, the complainers, the fraudsters, and the role addresses. Your open rates go up because the denominator shrinks to actual humans. Your sender reputation climbs. The emails you do send actually get seen.

One bad list can tank a sender reputation it takes six months to rebuild. One cleaned list, done right, can double your revenue per send by the next campaign. This is what Dragonfish does before your first email ever goes out.

Why DragonFish IP Resolution is different

Most IP resolution is just based on IP. Ours is superior because it is both deterministic and probabilistic: deterministic data for precision, probabilistic data for reach, sourced from the one IP data provider top experts in the industry consistently recommend.

• Daily access means you get a link to a Google Doc updated in real time ($199/mo minimum, $0.60 per lead). Monthly report is $99/mo minimum, $0.45 per lead.
• If you are a cold email client, we automatically connect leads to our system, but you can connect them to yours too for quick retargeting by email or social.
• We auto-filter out your current customers and intent-based leads, so you are not charged for those.

Powering our stack is data from Simplifi, a real-world media platform named "Best Results in 2026" and "Users Most Likely to Recommend in Summer 2026."

How Warm Email works

• Our standard cadence is 3 emails per week for 4 weeks (12 sends per contact per month). Max sent per day is your list size.
• We deep-clean the list first (28 checks per address), then write to one real person in your brand's true voice. Our emails sound human, so they actually land.
• We don't touch your current setup. We build a fresh, clean system beside it, on domains you own.
• List cleaning is charged separately, based on your original list size, using our standard List Cleaning pricing. It's a one-time charge added to Month 1.
• Setup fee: $997 per month for the first 3 months, or $2,500 if paid up front (save ~$500). Already a DragonFish cold email client? Setup is $997 once.
• Each additional product or category of products: $497 (for the brains). Email writing out of scope: $997.
• 3-month minimum commitment. Starting month 4, a 5% royalty on gross sales we generate.

How Cold (Intent) Email works

• Each intent lead gets up to 4 emails over the month, triggered by what people actually do, not a random calendar.
• You own the list, the domains, the pages, and the emails. Even if you leave.
• Setup fee: $997 per month for the first 3 months, or $2,500 if paid up front (save ~$500). Already a DragonFish warm email client? Setup is $997 once.
• Each additional product or category of products: $497 each (for the brains).
• 3-month minimum commitment. Starting month 4, a 2% royalty on gross sales we generate.
• If you're getting good results after the first 3 months, we can usually increase the number of intent leads per month.

What is Marketplace Capture?

When you sell on Amazon, Walmart or TikTok Shop, the marketplace owns the customer. You paid to win the sale, but you can't email the buyer, ask for a repeat order, or tell them about your next product. Marketplace Capture fixes that: it identifies your marketplace buyers, fully Amazon and Walmart compliant, and turns them into first-party customers on a list you own, then automates the retention marketing that brings them back.

• One-time-use QR stickers, not inserts. We use unique, single-use QR stickers that your supplier or 3PL applies to the product or box. They are far more engaging and work way better than package inserts or a QR code printed on the packaging. The sticker invites the buyer to register a warranty, claim a reward or one-time coupon, or enter a giveaway; they opt in with their email (and phone), and that identity is matched to their marketplace order.
• Fully Amazon and Walmart compliant. This is not a review-generation or review-manipulation program, and it never asks for or incentivizes reviews. More reviews can happen naturally when happy customers are engaged, but that is a by-product, not the purpose.
• Fraud-proof by design. Every code is unique and single-use, so coupons can't be shared or scraped, and every redemption is attributed back to the campaign.
• Automated retention. Captured customers flow straight into your DragonFish warm email system: cleaned, written to one real person in your brand's true voice, and sent at the right moment. Re-order reminders, cross-sells, launches, and review requests happen on your terms.
• You own the data. Verified first-party email and SMS contacts, revenue and redemptions tracked by campaign, and a customer relationship that no algorithm can switch off.
