1. Bad lines in the logo

When the characters and design elements in the logo are drawn or modified, great care should be taken by the graphic designer. The lines and dots inside the logo should be smooth and clean. In the logo design example below, you will see how the inside line of the letter does not have a curve towards it. This is one of the most common problems we see in poorly made logos.

Logo files are made up of many dots and lines. When the logo is small, these imperfections may not be significant, but as the logo gets bigger the issue becomes more obvious and problematic. You should have a graphic designer who will fix the curves and lines of the logo. Then use the new files to replace the problem logo.

2. Improper Alignment of Logo Elements

Since graphic designers create logos, they are composing letters and design elements. They have complete control over the sizing and alignment of objects. With all this control, and especially the number of elements or characters is likely to increase that something does not adjust as it should.

As with the "bad lines" example above, a small logo size can hide problems when compared to an extended version. But on the screen or in digital access, cutting your logo the wrong way causes it to look blurry (due to pixel interpolation, solid dark pixels are divided into multiple lighter pixels). Graphic designers can adjust the arrangement of elements using the Snap-to-Grid or Snap-to-Guide feature, functions available in Adobe Creative Cloud software. This process will ensure that items are arranged just like your logo.

3. Missing Font in Logo

A logo design should always be presented as a piece of artwork composed of lines and points or pixels. Unfortunately, this is not always the case. If a graphic designer used a particular font in your logo, you may not have that font on your, or your vendor’s, computer. A missing font often leads to it being substituted by another font available on the computer. It’s a major problem that prevents anyone who doesn’t have the font to see the logo properly. This even holds true for a graphic designer trying to fix the problem.

As a logo is designed, fonts are commonly used either as they are, or as a starting point to be modified for the design. The important step in the logo design process is to “outline” the letters being used in the logo so they become a piece of artwork rather than letters you can edit by typing. Once this process has been done, it is not reversible and the font will no longer be required to view and reproduce the logo. Be aware that fonts can cost between $20 and $150 or more just for one weight, such as Helvetica Neue Bold.

4. The Incorrect Logo File Format

Another one of the most common issues we see with logos that are supplied to us is that they are not in the correct file format. If your graphic designer comes to you and says “it’s not the right format” it can mean a few things. However, if your designer intends on using the logo, it is not going to work.

The most common incorrect file format we receive is a raster logo such as a .jpg rather than a vector logo, such as a .eps. A .jpg logo might be fine if the resolution is high enough and it does not require being produced on a color or transparent background. Vector logos will offer a graphic designer the most options, including saving the artwork to other file formats. A vector logo can be enlarged or reduced infinitely without losing quality.

5. The Incorrect Logo Color Format

A less common but potentially more challenging logo file format issue is the color mode. A logo that is being printed on paper, on a t-shirt, or being included on a website will have different color spectrum requirements. Some can be easily converted from one to another but others cannot. Again, a vector logo will offer a graphic designer the best chance to fix the issue.

Introduction

1. Improve your website

• Explain who you are and what you sell
• Entice a potential customer to buy
• Make it easy to buy a product or service
• There is a way to easily contact sales or customer support with questions

2. Invest in your business

3. Increase your advertising

4. Raising prices

• How much does it cost you to make a product
• How much does it cost to deliver
• Costs for running a business - including administration and employee salaries
• Competitive price
• The last time you raised a price

5. Follow the 80/20 rule

6. Cut costs

• Are there areas where you can improve efficiency?
• Negotiate cheap products or services?
• Will adopting new software or renting a service save you money in the long run?

We are recently developed a site into the gatsby. basically contact us feature is common in all website.
and we are implementing Mailchimp because it's a very popular platform in email market.

So, I will show you how to setup a Mailchimp in the Gatsby site.

## Using gatsby-source-mailchimp

Use your Mailchimp API key to download your campaigns into Gatsby’s GraphQL data layer!

Install the package by running the following command: `npm i gatsby-source-mailchimp --save`

### How to configure
Once the installation is complete, you can now add this plugin to your gatsby-config.js, like so:

Configure mailchimp Key and add this {resolve: `gatsby-source-mailchimp`} into the plugins array. code looks like

```
module.exports = {
  // ...
  plugins: [
    {
      resolve: 'gatsby-source-mailchimp',
      options: {
        // Avoid including your key directly in your file.
        // Instead, opt for adding them to .env files for extra
        // security ;)
        key: 'asd712jdas90122jdas90122jkadsd1-usXX',
        rootURL: 'https://usXX.api.mailchimp.com/3.0',
      },
    },
  ],
  // ...
}
```

Above is the minimal configuration required to have it work. By default,
This plugin was made out of a specific necessity, so it doesn't cover all of Mailchimp’s data sources, focusing only on campaigns.

this plugin are provide few options. you can refer here.

## Using `.env` variables to hide your key
If you don’t want to attach your API key to the repo, you can easily store it in .env files by doing the following:

```
// In your .env file
MAILCHIMP_KEY = 'asd712jdas90122jdas90122jkadsd1-usXX';
```

```
// In your gatsby-config.js file
require('dotenv').config({
  path: `.env.${process.env.NODE_ENV}`,
});

module.exports = {
  // ...
  plugins: [
    {
      resolve: 'gatsby-source-mailchimp',
      options: {
        key: process.env.MAILCHIMP_KEY,
        rootURL: 'https://usXX.api.mailchimp.com/3.0',
        // ...
      },
    },
  ],
  // ...
};
```
