The Questions India-Based Teams Ask First
"Do you actually work IST hours?"
Yes. We are headquartered in Bhopal and our whole team works Indian Standard Time, so a call at 11am or 4pm IST is a normal working hour for us, not a stretch across time zones. For clients abroad we overlap in our evening and run everything else async.
"Is a local consultant better than a global agency for us?"
For India-based teams, often yes - not because deliverability changes by geography, but because you get same-timezone calls, invoicing in INR with GST, and pricing set for the Indian market. The technical work (authentication, reputation, infrastructure) is identical to what we do for clients worldwide.
"Can we work in Hindi?"
Yes. We work in both English and Hindi, so your team can discuss the technical details in whichever language is comfortable - on calls, in explanations, and in walkthroughs.
"Are you a real specialist or a general digital-marketing agency?"
We only do email - deliverability, authentication, and sending infrastructure. We do not sell SEO, ads, or social. That focus is the difference between a generalist agency that lists email as one service and a team that fixes inbox placement for a living.

Common Questions
Where is Postbox Consultancy Services based?
We are headquartered in Bhopal, Madhya Pradesh, India, and work Indian Standard Time. We serve clients across India and worldwide, so wherever your team sits, you get a specialist working your problem - with IST-hours availability for India-based senders.
Can you invoice in INR with GST?
Yes. Indian clients are billed in rupees with 18% GST on a proper tax invoice; international clients are billed in USD. Our retainer and audit pricing is published for both, so there are no surprises.
Can you fix a blacklisted domain or a Gmail spam-rate problem?
Yes. We diagnose the cause - spam complaints, compromised sending, list quality, weak authentication or infrastructure - request delisting where applicable, and put safeguards in place to prevent recurrence. If your Gmail Postmaster Tools spam rate is above the 0.3% threshold Google requires of bulk senders, we treat that as an urgent, root-cause fix.
Do you support ESPs and platforms like Zoho, Mailchimp, HubSpot, Klaviyo or Instantly?
Yes. We work across major ESPs and cold email platforms and adjust our recommendations to the sending limits and configuration options of whichever platform you use. Our approach is ESP-agnostic - the same authentication and reputation principles apply everywhere.
How fast can you start?
Most audits begin within 1-2 business days of the discovery call. Urgent issues like active blacklisting or a spam-rate spike are prioritized immediately.
Do you also handle email security - DMARC enforcement, anti-spoofing and BIMI?
Yes. Beyond inbox placement we run email security engagements: moving domains to DMARC enforcement without breaking legitimate mail, hardening against spoofing and BEC, security audits, and BIMI implementation so your verified logo appears beside your emails in supporting inboxes. Our free DMARC monitor keeps the reports flowing after the engagement ends.
