Sendgrid to Postgresql

Do you use Sendgrid to send, organize, manage and send out your organizational emails? Do you want to start generating actionable insights and analytics from your Sendgrid data? If so, then moving your data from Sendgrid to PostgreSQL, a robust database solution, might be a good first step. This blog post will show you two ways of connecting Sendgrid to PostgreSQL. This will enable you to evaluate both methods and choose the one which best suits your needs.

SendGrid is a cloud-based software that enables you to manage and deliver your emails without an email server. Sendgrid takes care of technical details like Internet Service Provider (ISP) monitoring, domain keys, feedback loops, etc, and allows you to track bounces, subscriptions, email opens, and spam reports. It also has a reporting feature that enables you to gather high-level real-time analytics on emails. Sendgrid is offered as a Freemium service, so users can gain a base-level of functionality free-of-charge but are required to pay to gain access to additional tools and capabilities.

Key Features of Sendgrid

  • Analytics Feature: Sendgrid provides statistics that enable you to track high-level analytics on your emails.
  • Unsubscribe Tracking: You can add subscription links to the bottom of your emails through Sendgrid. Sendgrid also helps you track subscriptions to ensure that those respondents that have unsubscribed are not contacted in the future.
  • Email Template Engine: Sendgrid provides an email template engine that helps you easily edit and create transactional email templates.
  • Reputation Monitoring: Sendgrid has a reputation monitoring feature that enables you to quickly check the level and effectiveness of your email sending practices to ensure that they adhere to a high standard. This score is based on your spam, bounce, block, and invalid rates.

Introduction to PostgreSQL

Postgres is a popular relational database that uses a variant of SQL in its operations. Postgres can store and scale different workloads, making it a very versatile relational database. This versatility makes Postgres very useful in many instances, from use for small applications to large-scale data warehousing. Postgres also has an architecture that encourages extensibility. Thus, enabling you to incorporate code from other languages without recompiling the database. Its extensibility also enables you to define your own data types. Postgres is also ACID-compliant and able to run on all the major operating systems.

Key features of Postgres

  • ACID-Compliant: Postgres is ACID-compliant and so ensures that your transactions are handled in a timely and efficient manner.
  • Open Source: Postgres is fully open-source and has an active community to help with efficiency tips, bug resolution, etc.
  • Extensibility: Postgres is very customizable and so can more readily incorporate new functionality into its system.

Moving Data from Sendgrid to PostgreSQL

Moving Sendgrid’s data to PostgreSQL can be done using two methods.

Method 1: Using ETL Scripts to Connect Sendgrid to Postgresql

This is a simple 3-step process that involves extracting your Sendgrid data through a REST API provided by Sendgrid followed by converting your data into a suitable format and loading it up into Postgres by using a staging table. This method of connecting Sendgrid to Postgresql has a few advantages and a few challenges as well.

Method 2: Using Hevo Data to Connect Sendgrid to Postgresql

A fully managed, No-code Data Pipeline platform like Hevo Data, helps you load data from Sendgrid for free (among 100+ Sources) to PostgreSQL in real-time, in an effortless manner. Hevo with its minimal learning curve can be set up in a matter of minutes making the users ready to load data without compromising performance. Its strong integration with various sources such as databases, files, analytics engines, etc gives users the flexibility to bring in data of all different kinds in a way that’s as smooth as possible, without having to write a single line of code.

Methods to Connect Sendgrid to Postgresql

These are the methods you can use to set up a connection from Sendgrid to Postgresql:

Method 1: Using Custom ETL Scripts to Connect Sendgrid to Postgresql

The broad steps in this approach are as follows:

Step 1: Extracting Sendgrid Data

Sendgrid provides a rich REST API from which you can extract your data. You can do this by directly interacting with the API or using a tool like Postman or curl. Sendgrid’s API exposes several endpoints that provide access to resources like spam reports, email statistics, etc. The data is returned in JSON format. Example code:

GET https://api.sendgrid.com/v3/categories/stats?start_date=2015-01-01&end_date=2015-01-02&categories=cat1&categories=cat2 HTTP/1.1

A response similar to the data below is obtained:

        "name": "cat2",

        "type": "category"

      }

    ]

  }

]

Step 2: Preparing Your Data

The data from Sendgrid is in JSON format and so you may need to flatten any parts that are nested before feeding it into Postgres. You may choose to convert your JSON file into CSV format to make it easier to ingest it into Postgres. Alternatively, you can feed the JSON directly into a SQL statement that will extract the data and feed it into a table. An example of such code is: 

with json (doc) as (

   values 

    ('[

      {

        "id": 08133………

}

    ]'::json)

)

insert into TABLE1 

You will also have to make sure that your data types in Postgres match their corresponding types from your Sendgrid data. Postgres provides support for many of the well-used data types today. Additional information on Postgres data types can be found here

Step 3: Loading Your Data into Postgresql

You can load your data into Postgres through the following steps:

  1. Create a staging table:

     

    Eg. CREATE TABLE TABLE_NAME
    
    (COLUMN_1 TYPE,
    
    COLUMN_2 TYPE……)
  2. Use the COPY Sql command to load your data
    Example code:

     

    COPY table_name
    
    FROM 'file_name.csv' HEADER CSV DELIMITER ',';

Limitations of using Custom ETL Scripts to Connect Sendgrid to Postgresql

  • Real-time Data Load: You will have to write additional code to configure cron jobs to achieve real-time data load functionality. This makes the manual process even more cumbersome.
  • Time-Consuming: The manual method of moving data from Sendgrid to Postgresql uses up a lot of time since you have to manually write a lot of code to perform your ETL. This is problematic when you have tight deadlines to enforce.  
  • Difficulty with Data Transformations: You cannot perform fast data transformations like currency/date conversions under this method. You would need to invest additional developer bandwidth to achieve this.
  • Maintenance: This method requires constant monitoring as it will return inaccurate data will be returned if the Sendgrid API is down or if there are any connectivity issues
