Email marketing services from setup to scale
Every engagement starts with the correct technical foundation, then builds campaign strategy, automation, and ongoing management on top of it. No campaigns launch until deliverability is confirmed.
Email Automation Setup
Welcome sequences, drip campaigns, behavioural triggers, and lifecycle flows built in your platform
Core
Email Automation Setup
Welcome sequences, drip campaigns, behavioural triggers, and lifecycle flows built in your platform
Email marketing automation is what separates a one-time campaign from a revenue engine. Siznex builds full automation workflows in your chosen platform covering every stage of the customer lifecycle. Automations are mapped to your audience journey, triggered by behaviours, time delays, or CRM events, and A/B tested before full deployment. Every flow includes clear success metrics and is reviewed monthly to improve open rates, click-through rates, and conversion performance.

End-to-end campaign strategy, copywriting, design, segmentation, and performance tracking

Email Marketing Technical Setup
SMTP configuration, DKIM, SPF, DMARC, dedicated IP setup, and full deliverability infrastructure
Technical
Email Marketing Technical Setup
SMTP configuration, DKIM, SPF, DMARC, dedicated IP setup, and full deliverability infrastructure
Email marketing technical setup is the foundation that determines whether your campaigns reach the inbox or disappear into spam. Siznex configures your dedicated sending infrastructure, implements DKIM (domain key signing, sets up SPF (Sender Policy Framework) records, and configures DMARC (Domain-based Message Authentication, Reporting, and Conformance) policies. We also manage IP warming, email reputation monitoring, and spam score reduction. Without correct technical setup, even the best email marketing campaign will fail to deliver results because it never reaches the inbox.

Email List Building and Segmentation
Target audience definition, contact data collection, email verification, and CRM import
Sending email to the wrong audience is the fastest way to destroy sender reputation and generate spam complaints. Siznex defines your target audience and target industry, collects business and verified contact data from approved sources, extracts and validates email addresses for bounces and disposable domains, segments and organises lists by industry, company size, buying intent, and engagement history, then imports the structured, verified list into your chosen CRM or email marketing platform ready for campaign launch. List hygiene, suppression management, and bounce removal are maintained throughout every campaign cycle.

Email Deliverability Optimization
Inbox placement guarantee, spam score reduction, sender reputation monitoring
Email deliverability optimization is the ongoing process of ensuring your emails consistently reach the primary inbox rather than promotions tabs, spam, or junk folders. Siznex audits every factor affecting inbox placement: DNS authentication records, sending IP reputation, domain age and history, email content spam triggers, list quality, engagement signals, and sending patterns. We implement systematic improvements, monitor sender scores across major providers (Gmail, Outlook, Yahoo), track blacklist status, and maintain the technical infrastructure that keeps your email deliverability above 97 percent inbox placement.

Platform selection recommendations are made during the free consultation based on your specific business requirements.
This is right for you if…
Siznex works with businesses at different stages of email maturity — from complete greenfield setup to rescuing broken deliverability from a previous agency.
E-commerce and DTC brands
You have a Shopify or WooCommerce store, an existing email list you are undermonetising, and need properly structured automation flows — abandoned cart, post-purchase, win-back — running on Klaviyo or Mailchimp.
B2B and SaaS teams
You need outbound lead generation email sequences, lifecycle nurture for trial users, or HubSpot and ActiveCampaign automation that feeds your sales pipeline with qualified conversations, not just opens.
Anyone with a deliverability problem
Your emails are landing in spam, your domain is on a blacklist, or your open rates collapsed after a platform migration. You need the technical foundation fixed before any campaign strategy can work.
Email marketing platforms we work with
Platform recommendation is based on your business model, list size, CRM stack, and automation complexity. We do not push a single tool, we match the platform to the requirement.
Email deliverability starts with correct technical setup
Over 20% of all legitimate marketing emails never reach the inbox due to missing or misconfigured authentication records. Siznex configures the complete technical foundation that inbox providers require before your campaigns go live.

How we build your email marketing programme
Every email marketing engagement follows a systematic five-step process from audience identification through live campaign launch. No campaign goes live without a clean list, correct technical setup, and confirmed inbox placement.
Identify your exact target audience, industries, company sizes, job titles, and intent signals. Define the message and value proposition for each segment before any data collection begins.
Collect business and contact data from verified sources. Extract and validate email addresses against bounce, disposable, and catch-all filters. Only deliverable, verified contacts enter the list.
Segment and organise email lists by industry, company size, buying stage, and engagement level. Proper segmentation ensures the right message reaches the right audience and protects sender reputation from irrelevant sends.
Configure domain authentication records. Import lists into your CRM or email marketing platform. Confirm primary delivery rate above 97% across Gmail, Outlook, and Yahoo before any send.
Launch email campaigns and automation sequences with full tracking. Monitor open rates, click rates, reply rates, and conversion performance. Iterate weekly based on data.
Your emails reach the inbox. Every time.
inbox deliverability and domain security are not optional extras. They are the foundation that determines whether any email investment returns value or is silently blocked by inbox providers.
Deliverability assurance
Siznex maintains above 97% primary inbox delivery across all managed accounts. Deliverability is monitored continuously across Gmail, Outlook, Yahoo, and Apple Mail using real-time sender testing tools. Any drop in inbox placement triggers an immediate technical review. No campaign is sent on a domain that fails pre-send deliverability checks.
Domain security and authentication
Correct email authentication prevents domain spoofing, phishing attacks using your brand name, and the reputation damage that comes from emails being sent in your name by unauthorised parties. Siznex implements and maintains the full authentication stack: domain authentication records, and monitors DMARC aggregate reports to detect any unauthorised use of your sending domain.
