# Best Email Testing Software - Page 2

*By [Yukta Rustagi](https://research.g2.com/insights/author/yukta-rustagi)*


Email testing software helps businesses preview and test emails before they are sent to recipients to help build the most effective email campaign and maximize ROI (return on investment). To accomplish this, email testing software provides an editing platform for checking an email for potential issues prior to distribution. Common error inspections include spelling, grammar, formatting, design, and coding. During the testing process, email testing software delivers the email in a simulated SMTP server.

Marketing and sales teams utilize email testing software to ensure email campaigns are error-free and optimized for success. In addition to testing, email testing solutions typically provide supplementary email deliverability analytics and audience data. Many email testing solutions offer [A/B testing software](https://www.g2.com/categories/a-b-testing) integration for deeper insights into email campaign comparisons, including subject lines, email content, and link bounce rates.

Email testing software pairs well with [email deliverability software](https://www.g2.com/categories/email-deliverability), which dives further into monitoring the reception of an email campaign by measuring the spam rate, open rate, and delete rate of an email campaign. (Email testing software also examines potential spam issues through comprehensive testing via simulated spam filters.) Email testing software can also be integrated with [email marketing software](https://www.g2.com/categories/email-marketing) which streamlines the process of sending bulk email campaigns into one simple platform.

To qualify for inclusion in the Email Testing category, a product must:

- Provide a preview version of an email to test email design, code, and formatting
- Offer spam testing and deliverability testing
- Provide an email editing platform
- Provide email analytics that measures campaign performance

### 11. [Warmup Inbox](https://www.g2.com/products/warmup-inbox/reviews)
Warmup Inbox is an email warmup service that automatically raises your email sending reputation through our network of inboxes talking to each other. The process of preparing an email address for general use or email outreach is commonly referred to as “Warming Up” an inbox, where you take a number of steps to ensure that an email address does not become deactivated, blacklisted, or automatically marked as spam when it begins to send outgoing messages to other recipients. This process is typically done with newly created email addresses but also benefits older email addresses who have been having issues with email deliverability, in that a noticeable portion of their outgoing mail is either landing in a spam folder or blocked entirely by an email server due to either being blacklisted or associated with a domain that has a poor reputation.

Real-time delivery events via webhooks. Built for developers who need deep integration into existing systems. - Deep observability. Inbox placement per ISP, bounce breakdown, delivery rate monitoring, complaint tracking, with timestamps and error codes, not just "sent" and "failed." - Local support. Our team is in Indonesia. Same timezone. Same language. Reachable during your business hours. - Rupiah pricing. No currency risk. No conversion overhead. Predictable costs for Indonesian enterprises. # DEPLOYMENT OPTIONS Cloud, hybrid, or full on-premise.

### 20. [PilotMail](https://www.g2.com/products/pilotmail/reviews)
I am excited to introduce to you PilotMail. PilotMail is a HTML email testing and code builder tool that help busy email developers, designers and digital/email marketing agencies to simplify the process of coding, testing, troubleshooting and delivering perfect HTML emails. If you are like us, spending a lot of time crafting beautiful marketing emails or transactional email templates, then you must have the first-hand experience of difficulty in setting a smooth workflow for building perfect HTML emails. We ended up using multiple tools and services to make sure HTML email is optimised, cross-platform compatible and production-ready (CSS inlined, etc). Generally, a typical workflow included: - A code editor to write HTML/CSS code. - Linter to make validate your HTML/CSS code. - Online file storage provider to host email assets like images, etc. - CSS Inliner to inline all CSS styles. - Email Preview Tool to send test emails to various email clients and check compatibility issues. Phew! quite a list to of things to do before we deliver one perfect email template! That’s why we decided to solve the problem and built PilotMail. PilotMail brings all these tools and services together at one place and streamlines the whole process of coding, testing and delivering HTML Email templates. Here are quick lists of benefits that PilotMail offers: - You can send test HTML emails to up to 10 recipients at once for design testing and debugging on real email clients. - Include a plain text version of your email along with the HTML part to test both scenarios easily. - Generate production-ready HTML email with CSS Inlining and more settings to optimise code. - View how your email looks right in your browser with Layout Viewer. - Easily edit HTML, CSS and Plain Text of your HTML email with Code Editor built specifically for editing HTML emails. - Manage & host all images, etc your HTML email uses at one place. Many mailing services or ESP like MailChimp, Campaign Monitor, ExactTarget, and Silverpop also offer email coding & testing integrated into their email delivery process, but there are often many steps involved. Secondly, depending on the ESP it may cost you a lot to maintain an account with the ESP, as you end up paying extra for email delivery features too which depending on nature of your newsletters you may not even require. Finally, you get tied to one particular ESP, whereas if you use PilotMail, you keep all your templates at one place but use multiple ESPs to run your marketing campaigns. Our own team is using PilotMail for all PSD to Email projects. So why not take PilotMail for a spin and never send a broken email again?
