EMAIL MARKETING

Deliverability & Data Validation

projx digital

A new notification on your phone. You have a new email from a brand you love. What is it that convinces you to respond to that notification?

Successful email marketing is not about the "Send" button; it is the discipline of deliverability + data quality + message strategy + timing + measurement. Every email that lands in spam, goes unopened, or reaches the wrong person erodes campaign performance as well as your domain reputation. It even damages a connection that could be built in the future.

At PROJX Digital, we do not leave the email channel to chance. With the awareness that customer data acquired in compliance with the law is the most valuable data, we build the communication network with precision. With our technology-driven approach, integrated modules on the X8 Core and our data validation workflow, we clean lists, strengthen sender identity, and carry the message to its target through segmentation and automation. We would love for you to experience an email marketing process with us that is anticipated, responded to, and effective.

COMMON ISSUES

projx digital

THE CAMPAIGN IS BELIEVED TO HAVE "GONE OUT" BUT IT NEVER REACHES THE INBOX; IN FACT, YOUR CONSUMER AND YOUR EMAIL NEVER MEET (WEAK DELIVERABILITY)

THE LIST IS BLOATED: HARD BOUNCES, DUPLICATIONS, RISKY ADDRESSES, PASSIVE AUDIENCE; AS A RESULT OF UNNECESSARY WORKLOAD, NO TANGIBLE RETURN IS OBTAINED

THERE ARE REPORTS BUT NO DECISIONS: "WHAT WORKED, WHAT DIDN'T?" REMAINS UNCLEAR, AND UNLESS THE LIST IS FILTERED, NO POSITIVE RESULT IS ACHIEVED

THERE IS NO SEGMENTATION; EVERYONE RECEIVES THE SAME MESSAGE → COMPLAINTS AND UNSUBSCRIBES RISE. THE CONSUMER FORMS THE PERCEPTION: "THIS BRAND DOES NOT KNOW ME, DOES NOT CARE, AND SHOWS NO ATTENTION"

SPF/DKIM/DMARC ARE MISSING OR MISCONFIGURED; SENDER IDENTITY WEAKENS

IMPACT

SPAM

The spam complaint rate rises, sender reputation drops, and the bond with the consumer weakens

COST

Sending costs rise, conversion drops, and motivation decreases

LATE DELIVERY

Over time, even your best customer may receive emails late or not at all, and the bond weakens or may even break

Our Service Scope
Bulk Email Sending

DELIVERABILITY ENGINEERING
The Road to the Inbox

The "invisible infrastructure" of email performance is built here. The "Send" button does not mean the job is done. Our goal is to deliver an email marketing process that has reached the inbox reliably, conveyed the message to the right person in the right way, and converted into action.

  • SPF / DKIM / DMARC setup and validation
  • Sending domain strategy (main domain vs subdomain)
  • Bounce/complaint management (hard bounce, spam complaint)
  • Sending volume and frequency plan (controlled ramp-up instead of sudden load)
  • When necessary, a domain warm-up plan

Note: "100% inbox guarantee" is not a realistic promise. Inbox placement is a combination of content, target audience behavior, reputation, and technical configuration. We stabilize the controllable areas with engineering. We then initiate communication with the right content and a well-timed campaign.

DATA VALIDATION AND
LIST HYGIENE

The "problematic records" on your list are not just wasted cost; they pull down your entire domain reputation. Before a campaign, we filter and classify the list. The recipient engaging with the content means correct personalization has been achieved. Irrelevant emails create the perception among consumers and customers that "I do not matter, I am not given attention".

Validation layers (typical):

  • Syntax check (format/spelling errors)
  • Domain/MX check (can the domain receive email?)
  • Risk classification (role addresses, disposable/temporary addresses, catch-all probability)
  • Duplication cleanup (unique person/unique consent principle)
  • Bounce history analysis (quarantining recurring problematic addresses)

Output: Deliverable list + risky list + excluded list + action plan.

In repeated email marketing processes, the list becomes more effective each time. During this period, we also continue our work to generate new data and grow your list each time.

KVKK AND İYS COMPLIANT
SENDING SETUP

Email marketing is as much about compliance as it is technical.

  • Consent-based database setup (opt-in logic)
  • Unsubscribe link and preference management (frequency + topic selection)
  • Process design compliant with İYS integration (per organization)

This section does not replace legal counsel; the goal is to set up your sending processes so they operate in compliance. In this area, you may receive support from our legal advisors, or we may work in an integrated manner with your legal advisors.

STRATEGY, SEGMENTATION AND
AUTOMATION SCENARIOS

Clean data alone is not enough; the right message must go out at the right moment. The result report gives us a meaningful signal about this.

Typical B2C flows

  • Welcome series
  • Browse/Cart abandon (browsing/add-to-cart/abandonment)
  • Post-purchase (thank you, usage suggestion, cross-sell)
  • Win-back (re-engaging passive users)

Typical B2B flows

  • Lead nurture (educational series)
  • Post-demo/proposal follow-up
  • Event/webinar series
  • Lifecycle segmentation (MQL/SQL/Customer, etc.)

Segmentation signals: purchase history, interest, behavior, location, company type, engagement scores. All of these form the foundation of the next communication.

TEMPLATE AND
CONTENT OPTIMIZATION

Email should not be "flashy"; it should be readable and clickable, meeting the right person at the right time.

  • Mobile-friendly HTML templates
  • Modular blocks aligned with corporate identity
  • Microcopy (UX Writing) and CTA optimization
  • Balance between visual weight and load performance (critical for deliverability)

REPORTING: "OPEN RATE"
IS NOT ENOUGH ON ITS OWN

On some clients, the open metric can be misleading. We tie the report to more solid metrics:

  • Click (CTR/CTOR), conversion, revenue/lead quality
  • Bounce rate (hard/soft), spam complaint rate
  • List growth and churn (unsubscribe)
  • Segment-based "winning message/creative/CTA" analysis

OUR PROCESS
First Cleaning, Then Sending (4 Steps)

1
LEARNING THE DATA SOURCE
AND INTEGRATION

Where is your data? In CRM, in ERP, in web forms? All of it must be made usable, auditable, and, if needed, segmentable.

  • Channel analysis: data flow map (web form, CRM, ERP, etc.)
  • Central pool: deduplicating customer data on the X8 infrastructure or in the integration layer
2
SMART DATA VALIDATION
(DATA VALIDATION)
projx digital
  • Format, domain/MX, risk classification
  • Duplication + bounce history
  • Preparing the list for segmentation
3
STRATEGY AND DESIGN
projx digital
  • Segmentation, scenarios, frequency
  • Responsive templates, content standard, CTA design
4
SENDING AND OPTIMIZATION
projx digital
  • Controlled volume/frequency, test plan
  • Learning → iteration loop (every campaign produces data)

projx digital
DATA

Flows integrated with CRM/ERP and other modules

SEGMENT

Segmentation and automation are managed through the panel instead of Excel transfers, so there is no tampering with the data

SECURITY

Data security and process standards are strengthened, workload is reduced, and storage is carried out securely

When needed, we also build integration architectures compatible with your existing systems.
SPF / DKIM / DMARC Decision Guide (Example DNS Schema)

The most critical foundation in email deliverability:
is the authentication of the sender identity.

After this stage, the right communication process begins with the right address.

SPF (Sending authorization)

SPF is the answer to the question, "Which servers can send email on behalf of this domain?"

  • There must be a single SPF record (two SPF records on the same domain is a serious error).
  • SPF can hit DNS query limits; it must be kept lean.
DKIM (Signature)

DKIM adds a cryptographic signature to the email.

  • Was the message altered in transit? Did this domain really sign it?
  • It strengthens inbox placement especially in marketing traffic.
DMARC (Policy + reporting)

DMARC decides "what should I do?" based on SPF/DKIM results and reports:

  • p=none (monitor/report)
  • p=quarantine (push suspicious mail to spam)
  • p=reject (reject suspicious mail)

PROJX migration standard

TEST
Set up SPF + DKIM
COLLECT REPORTS
DMARC p=none
CLEAN
Clean up problematic sources
STABILIZE
p=quarantine → once stable
MATURE
p=reject → once mature

Domain or subdomain?

Best practice for high-volume setups:

Corporate: @company.com
Marketing: a subdomain like mail.company.com

This way, marketing fluctuations affect the main domain reputation less
Example DNS format (with placeholders)

The following is only a "schema"; values vary depending on the email provider you use.

projx digital
SPF (TXT)

Name/Host: @

  • Value: v=spf1 include:YOUR_ESP_SPF
  • include:YOUR_MAIL_PROVIDER_SPF ~all
DKIM (TXT) (selector comes from the provider)

Name/Host: selector1._domainkey

  • Value: v=DKIM1; k=rsa;
  • p=PUBLIC_KEY_FROM_PROVIDER
DMARC (TXT)

Name/Host: _dmarc

Pre-launch checklist

Is there a single SPF, is the include count reasonable?

Is DKIM returning "pass"?

Is the DMARC report address working?

Is the From domain aligned with SPF/DKIM?

Is the unsubscribe mechanism (header + link) correct?

WARM-UP AND SENDING FREQUENCY DECISION MATRIX

A sudden volume spike is the shortest path to spam instead of the inbox. Warm-up teaches your domain the "trusted sender" signal in a controlled way. That is why we manage communication correctly without falling into spam or making people click the unsubscribe button.

Frequency: "Same frequency for everyone" is inefficient

Segment-based frequency is healthier:
  • · Very warm (engagement in the last 7–14 days): 1–3 per week
  • · Warm (30–60 days): 1 per week
  • · Lukewarm (90 days): once every 2 weeks
  • · Cold (90+): re-engagement; if no response, move to passive
Mini re-engagement scenario
  • 1. Ask for preferences (topic/frequency selection)
  • 2. Move the engaged user to the main flow
  • 3. Move non-engaged users to passive (reputation protection)
PROJX checklist before warm-up
  • · SPF/DKIM/DMARC complete
  • · List validation + duplication cleanup complete
  • · Unsubscribe flow is working
  • · UTM standard and reporting plan ready
  • · First 2 weeks: simple creative + simple CTA

Deliverability Risk Map: 12 Mistakes that Cause
Spam Placement and PROJX Countermeasures

How accurate and functional the list you have is, is directly proportional to how you use it. The mistakes below can disrupt inbox placement even "on their own"; when combined, their impact multiplies. We manage these areas with a pre-campaign checklist.

1
SPF/DKIM/DMARC missing or wrong

Risk: Weak authentication → spoofing suspicion
Countermeasure: Triple setup + alignment check + gradual DMARC tightening

2
Multiple SPF records / SPF lookup limit

Risk: SPF "permerror" → trust drops
Countermeasure: Single SPF record + include simplification

3
From domain not aligned with signing domain (alignment issue)

Risk: DMARC fails → spam/quarantine
Countermeasure: Setting up the From/Return-Path/Signing domain architecture correctly

4
Sudden volume spike on a new domain

Risk: Appears as a "bulk sender" before reputation is built
Countermeasure: Warm-up + gradual ramp-up + warm-audience priority

5
Weak list hygiene (high hard bounce)

Risk: Direct damage to sender reputation
Countermeasure: Data validation + bounce quarantine + duplication cleanup

6
Bulk sending to cold/passive audiences

Risk: Opens drop, complaints rise
Countermeasure: Re-engagement flow + gradual elimination of passives

7
Spam complaint rate is rising (wrong segment / wrong promise)

Risk: Drift from inbox to spam
Countermeasure: Segmentation + expectation management + content/offer alignment

8
Unsubscribe is difficult or not visible

Risk: Unable to opt out, the user presses "spam"
Countermeasure: One-click opt-out + preference management (frequency/topic)

9
Excessive images, weak text balance / heavy files

Risk: Filters and user experience are negatively affected
Countermeasure: Balanced content + optimized images + clean HTML

10
Bad link reputation (URL shorteners, suspicious redirects)

Risk: Link reputation drops
Countermeasure: Branded domain, clean links, avoid unnecessary redirects

11
Misleading subject line / aggressive language

Risk: Complaints and unsubscribes rise
Countermeasure: Right promise + clear content + A/B test + consistent tone

12
Measurement error (no UTM, no conversion definition)

Risk: Optimization is done by "gut feeling", budget is wasted
Countermeasure: UTM standard + GA4 conversion model + reporting discipline

Simply landing in the inbox does not make the operation successful.

At PROJX, the goal is not "not landing in spam",
but to produce sustainable inbox performance and measurable business outcomes.

With software developed specifically for your business
accelerate your operations and strengthen your sales processes.

FREQUENTLY ASKED QUESTIONS

Yes. Sending to risky/invalid addresses raises bounce and complaint rates. This, over time, pulls your domain reputation down and makes inbox access difficult even for good addresses. While you try to sustain your digital presence, that presence gradually becomes invisible.

No. Nobody can realistically give a 100% inbox guarantee. By correctly setting up authentication, list hygiene, warm-up, segmentation and content discipline, we bring the spam risk down to a controllable level. All the campaigns the brand produces internally, the bond it will build with its customer and the meaning it will create form the other side of this work.

No. X8 provides integration and data management advantages within the PROJX ecosystem. We can also design a setup compatible with your existing infrastructure (CRM/ERP).

It varies by industry, goal and list quality. The healthiest approach is segment-based frequency. That is, user habits and what the brand can respond with determine the routine communication. This is exactly where personalized campaigns shine. (warm audience more often, passive audience less often).
