If your email are landing in spam, your automations aren't converting, or your cold emails aren't reaching decision-makers, you're losing opportunities every day. I help businesses fix the systems behind email performance so more messages reach the inbox, generate responses, and drive revenue. Most businesses don't have an email problem. They have an inbox placement problem, an automation problem, or a customer acquisition problem. That why I help you in three critical areas that directly impact email performance and business growth: Email Deliverability Marketing Automation Cold Email Infrastructure ━━━━━━━━━━━━━━━━━━ EMAIL DELIVERABILITY ━━━━━━━━━━━━━━━━━━ If your emails are going to spam, open rates have dropped, or Gmail and Microsoft are blocking your messages, I can identify the root cause and fix it. Services include: • SPF, DKIM, DMARC, and BIMI implementation • Google Postmaster Tools analysis • Microsoft SNDS troubleshooting • Domain and IP reputation recovery • Gmail 550 5.7.1 error resolution • Blacklist monitoring and remediation • Inbox placement testing and diagnostics • Domain warm-up strategies • Sender reputation improvement ━━━━━━━━━━━━━━━━━━ MARKETING AUTOMATION ━━━━━━━━━━━━━━━━━━ Automation should generate revenue, not create complexity. I build and optimize automated email systems that help businesses convert leads, nurture customers, and increase retention. Services include: • Welcome and onboarding sequences • Lead nurturing workflows • Customer retention campaigns • Reactivation and win-back campaigns • Abandoned cart automation • Post-purchase email flows • SaaS lifecycle automation • CRM and email platform integrations • Segmentation and personalization strategies ━━━━━━━━━━━━━━━━━━ COLD EMAIL SYSTEMS ━━━━━━━━━━━━━━━━━━ Cold email success starts with infrastructure. Without proper domain setup, authentication, reputation management, and sending practices, even great outreach campaigns fail. Services include: • Cold email infrastructure setup • Multi-domain sending systems • Email authentication configuration • Domain warm-up strategies • Deliverability audits • Outreach platform configuration • Sending reputation management • Inbox placement optimization • Cold email troubleshooting ━━━━━━━━━━━━━━━━━━ RESULTS ━━━━━━━━━━━━━━━━━━ Over the past 13+ years, I've helped 327+ businesses optimize email infrastructure, improve deliverability, build lifecycle automations, and create scalable email systems that generate measurable business results. • 95%+ inbox placement achieved across Gmail, Outlook, and Yahoo • 73+ restricted or flagged sending accounts restored • Spam complaint rates reduced below 0.1% • Open rates improved through deliverability optimization and list hygiene • Helped businesses recover and protect critical email revenue channels ━━━━━━━━━━━━━━━━━━ PLATFORMS ━━━━━━━━━━━━━━━━━━ Klaviyo, HubSpot, Mailchimp Brevo, ActiveCampaign, ConvertKit, Salesforce, GoHighLevel SendGrid, Mailgun, Amazon SES Clay, Instantly, lemlist, Smartlead, apollo, qucikmail. Snovo Make, Zaipper ━━━━━━━━━━━━━━━━━━ LET'S TALK ━━━━━━━━━━━━━━━━━━ If your emails are landing in spam, your automations are underperforming, or your cold email system isn't producing results, send me a message. I'll review your current setup, identify the bottlenecks, and recommend the most effective path forward. — Debobroto Chowdhury
