Can you recommend attribution software for measuring CAC and LTV across paid social, email, and influencer campaigns?

Yes — for measuring CAC and LTV across paid social, email, and influencer, you generally want a tool that combines:

• multi-touch attribution (MTA) for channel conversion credit
• customer-level revenue tracking for LTV
• identity resolution / UTMs / coupon or affiliate code support for influencer and email
• ideally integration with ad platforms + your CRM + ecommerce/subscription stack

Good software options

1. Northbeam

Best for: ecommerce brands spending meaningfully on paid social and influencer.

Strengths

• Strong attribution across Meta, TikTok, Google, email, and influencer
• Good for blended CAC and cohort-based LTV analysis
• Helpful for DTC brands with multiple touchpoints

Watchouts

• Can be expensive
• Best fit if you have enough volume to justify it

---

2. Triple Whale

Best for: Shopify/DTC brands that want fast deployment and strong reporting.

Strengths

• Easy integration with Shopify, ad platforms, Klaviyo, etc.
• Tracks CAC, MER, contribution, and customer cohorts
• Useful for tying email and influencer together with paid social

Watchouts

• Attribution can be less flexible than more advanced tools
• Best if your stack is Shopify-centric

3. Northbeam vs Triple Whale

If your main need is accurate performance attribution across paid social + influencer, lean Northbeam.
If you want a more operational, dashboard-first DTC analytics layer, lean Triple Whale.

4. Ruler Analytics

Best for: lead-gen businesses and revenue attribution across longer B2B or high-consideration funnels.

Strengths

• Tracks journey from ad/email to lead to closed deal
• Better if CAC/LTV depends on CRM sales stages
• Works well for marketing + sales attribution

Watchouts

• Less tailored to ecommerce than Northbeam/Triple Whale

---

5. Dreamdata

Best for: B2B SaaS measuring CAC, pipeline, and LTV by channel.

Strengths

• Strong revenue attribution from first touch to closed-won
• Good for email, paid social, content, and partner/influencer-like channels
• Excellent for cohort and customer lifecycle analysis

Watchouts

• Primarily B2B/SaaS, not ideal for pure ecommerce

---

6. HubSpot Attribution + Revenue Analytics

Best for: teams already on HubSpot.

Strengths

• Native CRM + email + deal tracking
• Good enough for basic CAC/LTV reporting
• Easier if you already manage campaigns and lifecycle in HubSpot

Watchouts

• Not as strong as dedicated attribution platforms
• Less robust for influencer and paid social nuance

---

7. Branch / AppsFlyer / Adjust

Best for: mobile apps.

Strengths

• Strong attribution for app installs, in-app events, and LTV
• Good cross-channel measurement

Watchouts

• More mobile-app focused than ecommerce/CRM marketing

---

What to look for specifically for CAC + LTV

If you care about all three channels you mentioned, make sure the tool supports:

CAC

• Customer acquisition cost by channel/campaign
• Blended CAC and new-customer CAC
• Cost pulled from ad platforms and influencer fees

LTV

• Cohort LTV by acquisition source
• Revenue by first-touch / last-touch / multi-touch source
• Repeat purchase or subscription retention tracking

Influencer measurement

• Unique discount codes / affiliate links
• Post-purchase survey attribution
• Custom partner tagging
• Holdout or incrementality testing if possible

---

My practical recommendation

If you’re an ecommerce/DTC brand:

• Northbeam if attribution rigor matters most
• Triple Whale if you want simpler deployment and broad reporting

If you’re B2B/SaaS:

• Dreamdata
• Ruler Analytics if sales-led or lead-gen heavy

If you’re a mobile app:

• AppsFlyer or Adjust

One important caveat

No attribution tool will perfectly measure influencer and paid social alone, because:

• iOS privacy limits tracking
• email often gets over-attributed
• influencer traffic may convert later through another channel

For that reason, the best setup often combines:

• an attribution platform
• CRM/ecommerce data
• post-purchase survey data
• incrementality tests / lift tests

If you want, I can also give you:

1. a shortlist by company type (DTC, SaaS, app, lead gen), or
2. a comparison table of features and pricing ranges.
