The Question
Why It Matters
How PRSTO Helps You
01 / POSITIVE REPLY RATE
What's Your Positive Reply Rate?
The most important metric in cold email outreach.
Everything else feeds into this number.
It measures genuine prospect interest rather than
simply how many emails were sent or opened.
PRSTO provides campaign reporting and reply tracking
so you can measure meaningful responses.
With our managed service, we also review performance
and refine targeting and messaging to improve results.
02 / OPEN RATES
Are You Still Relying on Open Rates?
Open rates can be distorted by privacy protections,
automated image loading, and security systems.
An email marked as opened doesn't mean a prospect
actually read it or has any interest.
PRSTO emphasizes positive replies and real prospect
engagement instead of relying on open rates
to evaluate campaign effectiveness.
03 / INBOX PLACEMENT
Are Your Emails Reaching the Inbox or Spam?
An email marked as delivered may still land in spam.
If prospects never see your message,
they have little chance of responding.
PRSTO offers inbox placement testing to help
evaluate where messages land across major providers.
This helps identify deliverability problems
that may be limiting campaign performance.
04 / EMAIL PROVIDERS
Do You Know Which Email Providers You're Sending To?
Google Workspace, Microsoft 365, and other providers
use different filtering systems.
A campaign may perform well with one provider
while struggling with another.
PRSTO uses provider information and inbox placement
results to help identify differences in delivery.
Our managed service can use those findings
to guide campaign and infrastructure adjustments.
05 / VERIFIED EMAILS
Are Your Email Addresses Verified?
Invalid and outdated email addresses cause bounces,
waste sending capacity, and can damage
your sending reputation.
PRSTO combines B2B prospect sourcing with
email verification to improve list quality.
Our managed service handles prospect sourcing
and list preparation for your campaigns.
06 / TARGETING
Are You Reaching the Right Decision-Makers?
Even perfectly delivered emails won't generate
much interest when they're sent to people
who aren't a fit for your offer.
Better targeting improves relevance.
PRSTO provides access to a database of
450M+ B2B leads,
with filters such as job title, industry,
company size, and other business criteria.
We help build prospect lists around your
ideal customer profile.
07 / MESSAGE TESTING
Are You Testing 5–8 Email Variations?
Different subject lines, opening messages,
offers, and calls to action can produce
very different results.
Testing helps identify what generates interest,
provided campaign volume supports useful comparisons.
PRSTO supports multistep email sequences
and message variations.
You can test and refine your own campaigns,
or have our managed team develop messaging
and optimize it based on prospect responses.
08 / DOMAIN PROTECTION
Are Your Sending Domains Protected?
Poor sending practices can damage domain reputation
and affect future inbox placement.
Using your primary business domain for
high-volume cold outreach creates unnecessary risk.
PRSTO helps establish dedicated outreach domains,
separating prospecting activity from everyday
business communication.
Our managed service handles domain setup
and related configuration.
09 / MAILBOX INFRASTRUCTURE
Are Your Mailboxes Properly Configured and Warmed Up?
Sending too much too quickly can trigger filtering
and harm mailbox reputation.
Reliable outreach requires appropriate sending limits,
gradual ramp-up, and ongoing monitoring.
PRSTO provides mailbox warm-up capabilities
and controlled campaign sending.
With managed service, we handle mailbox setup,
warm-up coordination, and sending configuration.
10 / AUTHENTICATION
Are SPF, DKIM, and DMARC Configured Correctly?
These authentication standards help receiving
servers verify legitimate email.
Incorrect configuration can contribute to
delivery problems, even with a good prospect list.
PRSTO assists with SPF, DKIM, and DMARC
configuration as part of email infrastructure setup.
Our managed service handles the technical
configuration so customers can focus on sales.
11 / APPOINTMENT CONVERSION
Are Your Positive Replies Turning Into Appointments?
Positive replies show interest, but that interest
needs to become qualified conversations.
Timely, relevant follow-up is essential
to moving opportunities forward.
PRSTO provides reply management capabilities
and follow-up workflows to help keep
conversations moving.
You can manage responses yourself or discuss
available managed follow-up options.
