Link Building Outreach That Actually Gets Replies
Your link building campaigns start with emails that land. Warm your outreach mailboxes for better placement rates.
Key takeaways
- Should I use a separate domain for link building outreach? Yes, we recommend using dedicated outreach domains rather than your main client domain.
- How many link building emails can I send per day? After proper warmup, 50-100 emails per day per mailbox is sustainable.
- Will warming help with guest post outreach? Absolutely. Guest post pitches face the same deliverability challenges as link requests.
Link Building's Deliverability Problem
Link building is a numbers game. You might send 100 outreach emails to get 5 links. But what if half those emails never reach the inbox? Your effective outreach drops to 50, and your link acquisition suffers accordingly.
Link building outreach is high-risk for spam filters:
- Cold emails to site owners who never opted in
- Templates that look similar across campaigns
- Links to your client's content (spam signal)
- High volume from domains with limited history
Warmup: The Foundation of Successful Link Building
Top SEO agencies warm their outreach mailboxes before every campaign. WarmySender builds sender reputation so your link requests actually reach webmasters and bloggers.
Link Building Benefits:
- Higher Placement Rate: More emails land, more links acquired
- Better ROI: Same effort, more results
- Faster Campaigns: Links secured in less time
- Protected Domains: Outreach doesn't hurt client domains
SEO Agency Scale
Link building agencies often run campaigns for 10-20+ clients simultaneously, each requiring dedicated outreach mailboxes. Traditional warmup costs explode:
| Clients | Mailboxes | Monthly (Competitors) | Annual |
|---|---|---|---|
| 10 | 20 | $980-1,400 | $11,760-16,800 |
| 20 | 40 | $1,960-2,800 | $23,520-33,600 |
| 30 | 60 | $2,940-4,200 | $35,280-50,400 |
WarmySender: from $14.99/month, multiple mailboxes included.
