Why Mass Acquisition Email Works
For many years now, most marketers will tell you that B2B mass email doesn’t work. They claim that no one wants prospecting emails and that you will only destroy your email reputation and brand by driving customer acquisition through email.
These people couldn’t be more wrong about acquisition and brand awareness email. They just haven’t figured out how to use mass acquisition email correctly. Nor have they figured out how to maintain a strong email reputation and strong delivery into the inbox of their target audience.

Third-Party Platform Risk
Most email platforms send multiple customers’ emails over a single pool of IPs. One bad actor can damage the sending reputation for everyone using that mail server.
What Damages Your Email Reputation
It only takes one bad actor to impact everyone using the same mail server. Here are the main reputation
killers:

Bad/Hard Bounced Emails
High number of emails sent to bad email addresses
causing permanent failures. This tells ESPs and ISPs that you have not verified your
data, leading to lower IP and domain reputation.

Taking Control with Multiple SMTPs
What is SMTP?
SMTP (Simple Mail Transfer Protocol) is an application used to send, receive, and relay outgoing emails between senders and receivers. The SMTP relay service can resolve issues with email deliverability and IP reputation.
The first step in optimizing your email campaign is to take control over how your email is
sent. By selecting an email platform that enables you to leverage multiple SMTPs, you can
optimize delivery rates across multiple IP pools.
đź’ˇ Pro Tip: Not all SMTPs have the same inbox success rate for each emailprovider (Gmail, Yahoo, iCloud, Comcast, etc.).
Example: Multi-SMTP Strategy
If you’re sending 500,000 emails a week with three SMTP
providers:
- Route a third of your list across each SMTP provider
- Reduce the size and risk of each campaign segment
- If one SMTP gets shut down, investigate and reroute to another
- Complete campaigns with less outage time and sales loss
For higher volumes, you can take this a step further and buy several IP addresses associated with each SMTP provider, routing your email sends through both multiple SMTPs and IP addresses.
Email Marketing Best Practices
Regardless of your email platform or the SMTP providers and IP addresses you use, you need to manage your
sending reputation. This reputation will play a large role in how well your emails are delivered.

A core component of your Demand Generation strategy is to establish your company as a helpful
thought leader in the industry. You do this by creating compelling content that ultimately
generates qualified leads and profitable top-line sales growth.

A recent campaign that sent over 2 million emails for a client:
Drove more website traffic than any other marketing channel- Cost a fraction of paid media channels
- Only 3 SPAM complaints from 2+ million sends
- Less than 0.01% unsubscribe rate
By creating industry-leading research studies, key decision makers who received these emails viewed them as
relevant content—not spam.
