Most small businesses don't have anyone who actually owns their Google Workspace. Email breaks. Staff leave and still have access. Licences pile up for accounts nobody uses. Nobody notices until it's a problem. That's where I come in. I'm a Certified Google Workspace Administrator and DMARC Specialist with 195+ completed projects and a 100% Job Success Score. I help startups, small businesses, and growing teams set up, migrate, and maintain Google Workspace — from your first 5 employees to 100+, without the jargon, and without you needing a full-time IT person. THIS IS PROBABLY FOR YOU IF: - You're moving from Microsoft 365, Zoho, cPanel, or GoDaddy and want a clean migration with zero data loss - Your emails are landing in spam, or not arriving at all - Former employees still have access they shouldn't - You're paying for licences nobody's using anymore - Workspace is getting more complex as your team grows, and nobody's managing it - Google Support tried to help and couldn't fix it If any of that sounds familiar, here's what I can do for you: WHAT I DO → Workspace Setup — Domain verification, DNS, Gmail routing, and security configured right from day one, plus a live 1-hour walkthrough so you and your team aren't left guessing. → Email Migration — A seamless move from M365, Zoho, cPanel, GoDaddy, or Bluehost. Every mailbox, contact, and calendar comes across intact. Zero downtime, zero data loss. → Deliverability Fixes — SPF, DKIM, and DMARC audited and corrected. Most single-domain issues are resolved the same day. I once helped a client cut spam placement from 40% down to under 2%. → Ongoing Admin Support — A monthly retainer covering onboarding, offboarding, licence management, access control, and security monitoring, with priority response within 2–4 hours. → Workspace Health Check — A full audit with a plain-English report and a 30-minute debrief, delivered within 48 hours, so you know exactly where you stand. Whether you're a 5-person startup or a 100-person team, I scale the approach to fit — no unnecessary complexity, no paying for more than you need. If you'd like ongoing support after we've worked together, I'm happy to put together a custom monthly proposal based on your team size. WANT TO TALK IT THROUGH FIRST? You can book a consultation directly from my profile. We'll go through your Admin Console or DNS settings together, troubleshoot spam or delivery issues, and map out next steps — no pressure, no ongoing commitment. A BIT ABOUT MY BACKGROUND Before Google Workspace, I spent a decade managing DNS and email infrastructure across cPanel and Plesk for hundreds of clients. That background means I catch root-level routing and authentication issues that most Workspace consultants miss entirely. I'm completely independent — not a reseller, no commissions, nothing pushed on you that you don't need. Just honest advice based on what your business actually requires. WHAT CLIENTS SAY "Fixed in 10 minutes what I couldn't solve in 2 hours." "Solved what Google Support couldn't fix in a week." "He was quick and extremely knowledgeable. Will work with him again when a new problem arises." "I'm so grateful I found Shrikant — knowledgeable, quick, easy to work with, and flexible." Message me your domain name and a quick summary of what's going on. I'll reply within a few hours and tell you honestly whether I can help.

Most freelancers set up cold email campaigns and hope for replies. I build cold outreach systems that connect deliverability infrastructure, automation, CRM tracking, and conversion logic, so you don't just send emails, you build a predictable pipeline. ⭐⭐⭐⭐⭐ "Susan is the best email marketer. I was hoping to get replies from leads, and I got them. We'll hire her again for future projects." - Gunjondev Here's the TRUTH most people learn the hard way: Your cold email campaign is only as strong as your 'Deliverability'. It doesn't matter how good your copy is. It doesn't matter how targeted your list is. It doesn't matter how perfectly timed your follow-ups are. If your emails aren't reaching the inbox, nothing works. Domains get burned. Emails land in spam. Sender reputation collapses. Leads never see your message. Replies never come. And most people never figure out why. I fix that, at the infrastructure level, before it costs you pipeline. Email Deliverability isn't a setting you toggle. It's a SYSTEM you build, and most cold email setups skip it entirely. Proper Email deliverability means: → Every sending domain is authenticated - SPF, DKIM, DMARC, MX records → Every inbox is warmed up correctly before a single prospect email is sent → Sending volume scales gradually, not blasted out cold on day one → Domain reputation is monitored continuously across Gmail and Outlook → Bounce rates stay below 2% and spam complaints stay near zero → Your emails land in the primary inbox, not spam, not promotions Email Warm-up is where most cold email infrastructure fails. Skipping warm-up or rushing it destroys sender reputation before your first campaign even launches. I run structured inbox warm-up using Instantly.ai and Smartlead, building domain authority progressively until every mailbox is ready to send at full volume without triggering spam filters or ISP throttling. This is the foundation. Everything else sits on top of it. Here's what I build: 🔴 Email Infrastructure & Deliverability → Domain and inbox setup (Google Workspace / Outlook) → SPF, DKIM, DMARC, DNS authentication, correctly configured → MX records setup & email authentication verification → Inbox warm-up & mailbox warm-up via Instantly.ai & Smartlead → Sending rotation across multiple warmed domains → Gmail inbox placement & Outlook inbox placement monitoring → Spam placement diagnosis & fixing → Blacklist recovery & sender reputation repair → Deliverability audits for underperforming sending environments → Ongoing domain health monitoring & maintenance 🔴 Cold Outreach Setup (Instantly | Smartlead | Apollo | Clay) → Multi-inbox campaign architecture → Safe sending limits & domain protection → Lead sourcing & enrichment workflows → Verified lead list building → Clean data to reduce bounce rates → Cold email sequence writing & follow-ups 🔴 Campaign Management & Optimization → Cold email A/B testing → Open rate & reply rate optimization → Cold email analytics & performance reporting → Sequence structure & messaging flow → Reply handling logic & inbox management → Fixing broken campaigns & underperforming sequences 🔴 Lead Generation & List Building → B2B lead list building via Apollo io, Clay com & Hunter io → Lead verification & hygiene enforcement → ICP definition & prospect segmentation → Lead enrichment & cold email personalization at scale → High-volume cold outreach infrastructure I don't just "send emails." I build systems that turn cold outreach into consistent revenue. HOW I WORK: - I'm available 30+ hours per week and respond within 4 hours. - Before any work begins, I send you a project BRIEF outlining exactly what I'll build, the steps I'll take, and what the final deliverable looks like, you APPROVE it before a single hour is billed. - Every project is delivered with a full handoff document, a written SOP covering how your system works, how to manage it going forward, and what to monitor. You own it completely. No ongoing dependency on me required. If you're: ✔ Starting cold email from scratch ✔ Fixing spam and email deliverability issues ✔ Landing in spam despite warm-up attempts ✔ Scaling to high-volume cold outreach ✔ Getting views but zero replies on campaigns ✔ Dealing with blacklisted or burned domains ✔ Cleaning up broken outreach infrastructure ✔ Unsure if your SPF, DKIM, or DMARC is set up correctly Let's build it properly. Before messaging, please share: ● Your target audience ● Your current setup ● Your goal (meetings, demos, sales) I'll tell you exactly what structure makes sense. Cold email should be a growth channel, not a gamble. Sound like a fit? Click "Invite to Job" or send me a message & let's build your strategy.

Email deliverability consultant hiring guide

Email deliverability consultants handle technical setup (SPF, DKIM, DMARC), sender reputation management, and strategic optimization for email management. Critical for businesses running email marketing, cold outreach, or transactional campaigns, these experts diagnose authentication issues and improve placement rates.

What does an email deliverability consultant do?

An email deliverability consultant is a specialist who helps businesses ensure their emails land in recipients' inboxes instead of spam folders. They optimize email infrastructure, configure authentication protocols such as SPF, DKIM, and DMARC, and monitor metrics like open and bounce rates.

For companies running email marketing, cold email outreach, or e-commerce campaigns, email deliverability experts play a critical role in maintaining sender reputation. They often provide domain warming strategies, manage relationships with ESPs like Gmail and Outlook, and perform hands-on remediation to remove blacklists and improve long-term email performance.

How to hire an email deliverability consultant on Upwork

Finding the right email deliverability consultant can transform your email performance from destined to spam folder to inbox-ready. Upwork makes it straightforward to connect with specialists who’ve solved every type of deliverability challenge. Here's how to hire an email deliverability consultant on Upwork.

Step 1: Post a job

A well-crafted job post is essential for attracting email deliverability consultants who have the specific technical expertise your project requires. The more precisely you communicate your challenges, the faster you'll connect with specialists who can solve them.

  • Review this email marketer job description as a starting point

  • Customize the draft with your specific deliverability challenges, such as high bounce rates or spam folder placement

  • Include must-have skills like SPF/DKIM/DMARC expertise and familiarity with your specific ESP platform

  • Share your expected budget and timeline

Use our Job Post Generator, powered by Uma™, Upwork's Mindful AI, to speed things up. Describe your needs in a few sentences and Uma will draft a tailored email deliverability consultant job post for your review.

Step 2: Evaluate candidates

Identifying the right email deliverability consultant requires looking beyond general qualifications to find proven expertise in solving problems similar to yours. Focus on candidates who can demonstrate measurable results from past deliverability projects.

  • Use Upwork's filters to narrow candidates by expertise level, hourly rate, and location

  • Uma can also help evaluate candidates by analyzing their profiles against your job requirements

  • Review portfolios specifically for deliverability case studies showing before-and-after inbox placement rates

  • Check client testimonials for mentions of successful remediation projects or improved open rates

You can use Upwork’s instant video interviews to screen applicants for a best-fit shortlist.

Step 3: Interview your top choices

Direct conversations reveal how a consultant approaches complex deliverability challenges and whether their problem-solving style aligns with your needs. Since email deliverability often intersects with marketing automation, reviewing marketing automation interview questions can help assess both technical depth and communication skills.

  • Ask about their diagnostic process for deliverability issues and experience with your specific email infrastructure

  • Request examples of past remediation projects with specific metrics like bounce rate reductions

  • Discuss their use of testing tools like mail-tester, GlockApps, or Google Postmaster Tools

Upwork Messages allows you to schedule and conduct live video interviews on the platform, with call transcripts and summaries available after the calls.

Step 4: Agree on scope and begin work

Before starting the work, you’ll want a firm contract in place to establish well-defined project parameters to protect both parties and set the foundation for a successful engagement. Taking time to document expectations up front prevents misunderstandings and keeps the project on track.

  • Choose between fixed-price for one-time audits or hourly contracts for ongoing optimization

  • Upwork's secure payment protection and contract workroom ensure you only pay for approved work

  • Set clear milestones for audit delivery, implementation phases, and post-remediation testing

  • Define deliverables like authentication setup, configuration documentation, and performance reports

How much does hiring an email deliverability consultant cost?

Freelance email consultants on Upwork generally charge $15 to $40 per hour for general email marketing work. The cost of hiring an email deliverability consultant depends on your project scope, the complexity of your email infrastructure, and the consultant's experience level.

Frequently asked questions

Is hiring an email deliverability consultant worth it?

Yes, hiring an email deliverability consultant is a worthwhile investment for most businesses that depend on email communication. For many businesses, hiring a consultant is more cost-effective than losing revenue to poor inbox placement. Even a short engagement to fix authentication protocols can deliver measurable ROI through improved email performance.

Email deliverability consultants bring specialized technical expertise that most in-house teams lack. They understand the nuances of authentication protocols (SPF, DKIM, DMARC), ISP filtering algorithms, and sender reputation management. For businesses sending high volumes of cold outreach or critical transactional emails, a consultant can diagnose issues in hours that might take an in-house team weeks to identify.

What's a good email deliverability rate?

The average email inbox placement rate is about 83%, meaning roughly 1 in 6 marketing emails never reaches the inbox, which is why top-performing senders aim for 95%+ deliverability. This high percentage means nearly all messages reach inboxes rather than being blocked or flagged by spam filters. High deliverability is essential for sales outreach, onboarding emails, and transactional messages.

Rates vary by industry, list quality, and email strategy. For example, highly engaged newsletters often exceed 98%, while cold email campaigns face tougher inbox placement challenges. Tracking metrics such as domain reputation, spam complaints, and open rates helps determine if your current strategies are working.

How do I fix email deliverability?

Improving email deliverability starts with proper authentication protocols (SPF, DKIM, DMARC) and a clean DNS setup. Consultants also recommend that you warm up domains, add segmentation to your email list, and use consistent sending patterns to build trust with ISPs like Gmail and Yahoo.

Other strategies include:

  • Content optimization. Avoid spammy subject lines and poorly structured email content

  • List hygiene. Remove invalid or unengaged addresses to reduce high bounce rates

  • Reputation management. Monitor blacklists, spam complaints, and sender reputation to maintain consistent inbox placement

How do I test my email deliverability?

Testing email deliverability involves more than just sending test emails to yourself. Professionals use mail-tester, GlockApps, or Postmaster Tools to measure inbox placement, spam filter triggers, and sender reputation.

A skilled consultant can run an email deliverability audit, simulate different email service providers (ESPs), and identify whether Gmail, Outlook, or Yahoo is filtering messages differently. They'll also analyze authentication protocols, DNS settings, and email content to find root causes.
