Mailtag vs GetProspect 2026: Which Tool Fits Your Cold Email Stack?

Mailtag is a Gmail and Outlook email tracker starting at $9.99/user/month. GetProspect is a B2B email finder database starting at $49/month for 1,000 contacts. They aren't really competitors: Mailtag tells you when a sent email gets opened, GetProspect finds the email address before you send anything. Pick based on which problem you actually have.

Mailtag vs GetProspect: Price and Features Side by Side

Mailtag and GetProspect solve different problems, so a raw price comparison is misleading unless you know which job you need done. Mailtag tracks emails you've already sent from Gmail or Outlook. GetProspect finds and verifies email addresses before you've written a word. The table below breaks both down on price, database size, and core function.

Feature	Mailtag	GetProspect
Starting price	$9.99/user/mo annual, $12.99 monthly	$49/mo for 1,000 credits ($34/mo annual)
Free plan	14-day free trial, no permanent free tier	50 verified emails/month, permanent free tier
Core function	Open, click, and attachment tracking inside Gmail and Outlook	Email finding and verification from LinkedIn and a 200M+ contact database
Real-world accuracy	Not applicable, it tracks sent mail rather than sourcing addresses	Claims 95%+, independent tests show 62-65% real-world hit rate per ColdIQ
Integrations	Gmail, Outlook, G Suite, CRM auto-BCC	HubSpot, Salesforce, Pipedrive, Zoho, Zapier, Chrome extension
Best-fit team size	Solo reps and small teams doing high email volume	SDR teams building outbound lists at 500+ contacts/month

How Much Does Mailtag Cost vs GetProspect in 2026?

Mailtag's Pro plan runs $9.99/user/month billed annually, or $12.99 billed monthly, per Capterra's 2026 pricing listing. GetProspect starts at $49/month for 1,000 verified email credits, dropping to roughly $34/month on annual billing, per GetProspect's published pricing tiers of Starter, Growth 5K, Growth 20K, and Growth 50K Agency.

Scale changes the math fast. A 5-rep team on Mailtag pays roughly $50-65/month combined. That same team pulling 5,000 verified emails a month on GetProspect's Growth 5K plan pays $99/month, a completely different budget line because it's solving a completely different problem. Compare that to Apollo.io's $49/seat baseline for a combined finder-plus-sequencer, and GetProspect looks cheap for pure sourcing at low volume but gets pricier per seat once a team scales past one license.

What Do You Actually Get With Each Tool?

Mailtag's feature set is narrow by design. It does one job and does it inside the inbox you already use.

• Unlimited email tracking with no watermark on paid plans, per SoftwareSuggest's 2026 listing
• Ping automated follow-up sequences that trigger based on open or no-open behavior
• Real-time desktop alerts the moment a prospect opens, clicks, or views an attachment

The gap: no built-in contact database. If you don't already have the email address, Mailtag can't help you.

• 200M+ contact database with a LinkedIn Chrome extension for one-click lookups
• Bulk domain search plus CRM sync to HubSpot, Salesforce, Pipedrive, and Zoho
• Permanent free tier, 50 emails/month, no credit card required

GetProspect has two real gaps. The 95%+ accuracy claim doesn't hold up under testing, independent benchmarks land at 62-65% real-world deliverability per ColdIQ and several G2 reviewers. And once you find the address, you're sending blind. There's no tracking layer, so you're pairing it with a tool like Mailtag or Hunter's tracking add-on anyway.

Which One Should You Actually Use?

Most people asking "Mailtag vs GetProspect" are asking the wrong question. If you already have a list and want to know who's opening your emails, Mailtag wins outright at $9.99/month. If you don't have a list yet, GetProspect is the only one of the two that builds it, but budget for the accuracy gap and plan on a verification pass.

The honest take: pairing them beats picking one. GetProspect fills the top of funnel, Mailtag tells you what's working once emails go out. Running both costs under $60/month for a solo operator, cheaper than a single ZoomInfo seat and more transparent about what each dollar buys.

If you're weighing Mailtag against GetProspect because you're building a cold email motion from scratch, the tool choice matters less than what happens after the email sends. Modern Inbound runs sourcing, verification, and sending as one system instead of three subscriptions stitched together.
