Email Deliverability Platform —Validate, Warm Up & Monitor

It makes sure your emails reach the inbox instead of landing in spam or bouncing. In practice, ValidPeak handles five things in one platform:

• Email validation — checks that every address on your list is real, active, and safe to send to before you launch a campaign.
• Domain warmup— gradually builds your sending reputation with Gmail, Outlook, and Yahoo if you're starting with a new domain or resuming after a long gap.
• DMARC monitoring — keeps your SPF, DKIM, and DMARC records aligned so inbox providers treat your messages as legitimate, not phishing.
• Blacklist monitoring — watches 200+ blacklists around the clock and alerts you the moment your IP or domain is listed.
• Campaign Intelligence — audits a campaign before you send it and gives you a predicted inbox placement rate, so you can fix problems before they cost you revenue.

Mailchimp, Klaviyo, and SendGrid handle the sending. ValidPeak handles the infrastructure that determines whether what you send actually arrives.

A standard domain warmup takes 4–8 weeks, depending on your target daily volume and how aggressively you want to scale. The process starts at a low daily volume — usually 50–100 emails per day — and increases gradually, giving inbox providers time to observe consistent, legitimate sending behavior.

ValidPeak automates the entire schedule. You connect your domain, set a target volume, and the platform handles the ramp-up — including simulated opens and replies that make the pattern look natural to Gmail and Outlook. By week 4, most domains reach 500–1,000 emails/day. By week 8, 5,000–10,000 emails/day is realistic.

The most common mistake is skipping warmup entirely or trying to accelerate it. A cold domain sending 5,000 emails on day one will trigger spam filters almost immediately — and the reputation damage can take months to undo.

DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email authentication protocol that tells Gmail, Outlook, and other providers what to do when someone sends an email claiming to be from your domain. Without it, anyone can send emails that appear to come from @yourcompany.com — which is exactly how phishing attacks work.

Beyond security, DMARC directly affects inbox placement. Google and Yahoo made DMARC compliance mandatory for bulk senders in 2024. If your domain isn't properly authenticated, a growing share of your emails will go to spam — even if your content is fine and your list is clean.

ValidPeak monitors your DMARC, SPF, and DKIM setup continuously, shows you every source sending on behalf of your domain (including third-party tools like Mailchimp or HubSpot), and flags misalignments before they cause problems.

Most senders find out the hard way — a campaign underperforms, open rates drop noticeably, and only after investigating do they discover a blacklist entry. By that point the damage is already done.

ValidPeak monitors 200+ blacklists continuously — including Spamhaus, Barracuda, SORBS, and Postmaster Tools — and sends you an alert in under 60 seconds from the moment your IP or domain appears on any of them. You don't need to check manually or run periodic audits; the platform watches in the background and tells you immediately when something changes.

Beyond the alert, ValidPeak provides step-by-step delisting guidance for each blacklist, since the process varies. Some delist automatically; others require a formal request with documentation.

You can use any tool on its own — just email validation, just DMARC monitoring, or just blacklist monitoring. The platform is modular and the Free plan gives you access to all of them at a base level.

That said, the biggest deliverability gains come from using them together. A validated list + a warmed-up domain + DMARC authentication + active blacklist monitoring compounds into inbox placement that no single tool achieves alone. That's why every paid plan includes all the monitoring tools together — the combined effect is greater than the sum of the parts.

There's a permanent Free plan — no credit card required, no time limit. It includes 200 validation credits per month, 1 domain for monitoring and warmup, and basic DMARC reports.

Starter starts at €28/month (billed annually, or €35/month billed monthly): 5 domains, 1,500 validation credits/month, daily blacklist checks, and 5 warmup accounts.

Pro starts at €142/month (billed annually, or €178/month billed monthly): unlimited domains, 20,000 validation credits/month, 10 warmup accounts, real-time alerts, API access, and priority support.

All paid plans include a 14-day money-back guarantee. There are also pay-as-you-go validation credit packs if you only need to clean a list once.

Yes — it's often the single most impactful thing you can do before a campaign. Here's why: Gmail tracks bounce rates per sending domain. Above 2% bounces, Gmail starts throttling your future sends. Above 5%, you're looking at active reputation damage that takes months to recover from.

ValidPeak customers typically see an 80–98% reduction in hard bounces after cleaning a list. Beyond bounces, removing disposable addresses and low-quality catch-all domains improves your open rate and engagement score — because every metric is now calculated against real, active people instead of dead addresses.

If you haven't validated a list in more than 6 months, treat it as stale. Email address decay runs at roughly 22% per year — meaning about 1 in 5 addresses on a year-old list may no longer be deliverable.

Regular email analytics tell you what happened afteryou sent — open rates, clicks, bounces. Campaign Intelligence tells you what's likely to happen before you press Send.

You connect or upload your campaign, and ValidPeak audits your recipient list health, domain warmup status, DMARC compliance, blacklist status, and authentication alignment. Based on all of that, it gives you a predicted inbox placement rate and a prioritized list of actions to improve it before the campaign goes live.

The model has been validated against 10,000+ real campaigns with 98.2% prediction accuracy. The average marketing team loses 23% of their campaign revenue to deliverability problems they could have caught beforehand — Campaign Intelligence exists specifically to close that gap.

Yes. ValidPeak works alongside your existing email service provider — it doesn't replace it. You keep sending through Mailchimp, Klaviyo, SendGrid, ActiveCampaign, Brevo, or wherever you currently send from.

For email validation, you clean your list in ValidPeak and upload the clean file to your ESP. For DMARC monitoring, you add a ValidPeak DNS record — your ESP setup doesn't change. For real-time validation on signup forms, you call the REST API directly. Official SDKs are available for Python, Node.js, PHP, Ruby, Go, Java, and .NET. The API handles up to 10,000 requests per minute with sub-200ms average response time.

A good reputation is worth protecting — and it degrades faster than most people expect. One batch of unvalidated imports, one unnoticed DMARC misconfiguration, one blacklist entry from a shared IP, or one aggressive campaign to a stale list can undo months of clean sending.

The monitoring tools — DMARC, blacklist, sender score — exist specifically for this scenario. They run in the background, tell you when something changes, and give you time to fix it before a campaign goes out. For senders who've already invested in deliverability, continuous monitoring is what keeps it there.

Think of it like a car with a good engine: you still check the oil. ValidPeak is the dashboard that tells you what's happening under the hood before something breaks.
