You & your ESP vendor: A match made at InboxArmy

InboxArmy is ESP agnostic. We do not recommend any specific ESP as we understand that ESP selection is a complex yet crucial process. At InboxArmy, we leverage our expertise to help you land the ideal ESP for your email marketing campaigns. Our team of experts understands your requirements, expectations, resources, and other crucial parameters. We follow a thorough process of testing, demos, and consultation before zeroing down on the best ESP for your email marketing campaigns

We’ll Help You Find an ESP That Best Fits Your Needs

Are you facing constraints with your current ESP? Do you have issues with reporting, data, or integrations? InboxArmy can help you evaluate and migrate to a better ESP. There is no such thing as the ‘best’ ESP. We help you find an ESP that best fits your specific needs without making things complicated.

Preliminary Audit

We do a preliminary audit to understand the prevailing challenges and things your current ESP is unable to deliver. For instance: The management is asking for certain kind of reports, you are blocked by your current ESP, you need an integration that is missing, you have issues with data, and so on…

Preliminary Audit

Vendor Research and Shortlisting

Once we identify the issues you are facing, we go out and identify the ESP that will suit your needs. There are literally hundreds of ESP vendors in the market each with a unique set of capabilities. We research and identify 3 ESPs that best match the requirements.

ESP Demo

We communicate with the shortlisted ESPs and arrange for a demo. The demo will help you objectively evaluate the best fit and make an informed decision.

ESP Migration

Moving to a new ESP can be difficult and time-consuming. We help you migrate from the current ESP to the new ESP hassles-free, thanks to our detailed migration checklist.

The ESP Migration Checklist

We do a preliminary audit to understand the prevailing challenges and things your current ESP is unable to deliver. For instance:

ESP Data migration

Training for new ESP


We organize training on the new ESP. The training is conducted by an expert from the ESP or our in-house expert.

Domain Authentication Setup icon

Domain Authentication Setup

When moving the sending domain to the new ESP, we will review and give guidance on setting up your SPF, DKIM and DMARC records to avoid any deliverability issues.

IP Warm-up Icon

IP Warm-up

The new IP needs time to be recognized by the ISPs. Hence in the first 2 to 4 weeks, we send out emails slowly so the new IP is sufficiently warmed up before sending in larger volumes.
