Struggling to use Zoho SMTP Settings for a reliable and efficient cold email campaign?

SMTP, or Simple Mail Transfer Protocol, is the backbone of email-sending operations. It dictates how emails route from your mail client to the recipient’s mail server. Incorrect settings can prevent emails from being sent or in spam folders and affect your cold email outreaches.

This guide will take you through a comprehensive setup and configuration process for Zoho SMTP settings with detailed instructions.

Let’s start!

What is Zoho SMTP Setting?

Zoho Mail SMTP settings are the server parameters necessary for sending emails through a Zoho Mail account using the Simple Mail Transfer Protocol (SMTP). They are crucial for users who want to configure their email clients or applications to send emails through their Zoho Mail account.

Why Should You Use Zoho SMTP Server Settings?

Using Zoho SMTP for cold email marketing solves critical challenges and offers such value that it is an indispensable tool for marketers.

Reliability in Email Delivery

When sending cold emails, one of the primary concerns is ensuring your emails consistently reach the recipient’s inbox. Zoho SMTP excels in this area by providing a dependable platform for outbound email delivery. The server repeatedly attempts to deliver emails until they reach the recipient, which is critical for cold email campaigns where every email counts.

Simplicity in Email Communication

You only need to compose your message and send it; Zoho SMTP handles the complexities of routing these emails through various servers until they reach their destination. This straightforward process eliminates complications, making it ideal for businesses focusing on cold email marketing, where speed and efficiency are key.

Assured Email Delivery

The persistence of Zoho SMTP in ensuring emails make it to the recipient’s server is invaluable. By retrying delivery until the email is received, Zoho SMTP maximizes the chances of your message being read.

Security and Control over Email Transmission

Zoho SMTP provides enhanced security features and allows for detailed configuration to handle sensitive information securely. This level of control is crucial for businesses that send out cold emails containing confidential content or proposals, ensuring that information remains secure and is only accessed by intended recipients.

Scalability for Large Organizations

For organizations that send a high volume of emails, Zoho SMTP is scalable to meet these demands. It supports bulk emailing, which is often necessary in large-scale cold email campaigns. This scalability ensures that as your business grows and the volume of your email communication increases, Zoho SMTP can handle this growth, maintaining high deliverability and reliability.

Troubleshooting Issues You Might Face with Zoho SMTP Settings

Let’s see how you can deal with some issues that you may face now and then with Zoho SMTP settings.

Unable to Connect to Outgoing Server/SMTP Server

Occasionally, email clients may attempt to connect to the default port 25 when setting up SMTP servers. For Zoho Mail, it’s essential to use the correct SSL or TLS ports, namely 465 or 587. If issues persist after verifying these port settings, obtaining traceroute details for smtp.zoho.com and contacting Zoho support with your account details and a description of the problem, including screenshots, can help resolve connectivity issues efficiently.

Relaying Disallowed Error

This error typically appears when there’s a mismatch between the email address used in your SMTP settings and the one registered as your account’s outgoing server. It can occur due to typographical errors in the email address during setup or if an incorrect email address is hardcoded in applications. You should double-check and correct the email address in your SMTP settings to rectify this to ensure consistency and proper email delivery.

Unable to Receive Emails from Website Contact Forms

Suppose you’re experiencing issues receiving emails from website contact forms. In that case, it might be due to your Web Host’s configuration, which could be set to handle emails locally due to matching domain names. 

To resolve this issue, you have to access your WebHost settings and select the Remote Email server option to indicate that emails should be delivered externally. Turn off any Local Email Delivery settings in your WebHost configuration to ensure emails from your web forms are routed correctly to Zoho Mail servers and reach your inbox as intended.

Duplicate Sent Copies

When using a different email client with smtp.zoho.com, sent emails are automatically saved in Zoho’s Sent folder. However, many email clients, like Gmail from Google Apps and Outlook, also save a local copy, resulting in duplicates. To prevent this, Zoho offers a setting to avoid saving another copy in the Sent folder. 

You will need to go to Settings, then to Mail Accounts, and under the SMTP section for your email address, uncheck ‘Save copy of sent emails.’ It stops the additional saving of sent emails, keeping your Sent folder clutter-free.
