Senders is the partner for teams serious about deliverability. We specialize in deliverability, scalability, and precision of cold email, helping you reach more inboxes without risking your reputation. ✨ Apollo's premier partner for Email Deliverability 📧

Senders at a glance: 

• Sent ~30 million emails last year for ~100 B2B companies
• Experience across nearly every business vertical

• Our clients include Seed to Series B+ startups backed by Greylock, Y Combinator, Foundation Capital, and many others

What we do: 

• High volume cold email outbound with exceptional deliverability – protecting domain reputation and staying out of spam
• Low volume Triggered Outbound – email sequences triggered by highly specific, real-time buyer behavior, backed by our deliverability-first mindset

When companies work with us:

1. Cold email is working, and they want to scale it safely
2. Cold email is underperforming, and they want to fix and scale
3. They want to get started with cold email and do it correctly from day one
4. They want to complement cold outreach with Triggered Outbound
5. They want to shift focus from cold email to Triggered Outbound

How we work: 

• We give clients access to our secure and scalable sending infrastructure, all the contact data (email addresses, etc.) they need, strategy, copywriting, and continuous deliverability monitoring/improvement/testing 
• Our job starts with the email send and ends when their prospect replies – the replies go straight to their in-house team for handling 
• Senders is not an outsourced SDR/BDR service, and we don’t price like one
